Memory storage technology has come a long way from compact disks. Or has it? In a recent paper, scientists report they were able to fit petabytes of memory onto a compact disk using new laser technologies and advanced material design. Is this the future of data storage? Let’s have a look.

I wish the development team much luck! I worked for years on holographic storage using similar polymers. We found writing the data would change its physical location in the medium, and the physical offset may not be constant. We could always recover the data, but the search algorithm was called far too often killing read performance.

We use holographic storage and computational technology all of the time. True, the physical nature of the storage medium is problematic for classical data storage and retrieval, but as far as a computational matrix, it actually proves ideal for quantum solutions to problems like classic cryptography and NP hard algorithms. We achieve this through the use of intra-phase encoding, which has the added advantage of making the indexing bit both encodable and addressable either laterally or temporally.

multi layer optical has been tried many times in the past. I remember around 2000 there was a company that had a 10 layer disk that could hold a lot but they never got off the ground. This 100 layer sounds more promising but like you say if the speed may be too slow right now. The one from the 2000s didn't even spin as it was in that format for simplicity and the availability of packaging would save money. The laser would do the aiming and all the work back and forth.

I used 8 track tapes, floppy disks we carried in school books on green screen computers, we used Dbase coding in computer class in the 80's. Then came casette tapes, and then CD's. Back then not too many people liked CD's, because it seemed the mediums were changing too fast. But, being able to change to a different track or song with a single button was pretty interesting. I know I always liked how amazing the sounds can be on vinyl. But being able to jog and enjoy music on a walkman was very enjoyable in the day. The only problems seemed the best way to run so they did not skip while you were running. There was a lot of changes going on back then and it was very fast. Portable phones had to be wired into cars or a large battery you would carry in a bag to now being able to walk around with it in your pocket. Modern smart phones are more powerful than most rooms full of computers back then. It will be nice to see how this new tech makes CD's more prevalant again.

The unit cells store electric charge. It's basically either DRAM: A transistor with a capacitor on one port. The capacitor stores charge that can be read out as current when the transistor is switched on. Flash: A field effect transistor with an additional floating gate. On that floating gate charge is stored or removed (via electron tunneling). That charge modifies the threshold voltage needed to tun the transistor on or off. What Sabine was thinking of is FeRAM (Ferro Electric RAM). It's similar to DRAM but uses a ferro electric gate. It's faster than Flash and longer lasting however it's storage density is far lower and it's much more expensive.

Sabine! I love your content! And finally you have touched on an industry that I was involved in and I have a few comments about this video (most of the time I'm intrigued but don't fully understand what you are talking about!). I implore you to read my comments: I was a software developer for Blu-Ray products for a major studio (I'm under NDA so i'm not sure if I'm able to tell you which one). In my opinion optical storage of any size is not coming back due to some inherent disadvantages. But let me explain the background: Compact Discs were popular because it delivered Digital quality music to the consumer and high capacity data for installation discs etc for computers. CDs were simply not large enough to play a movie even in SD (Standard Definition) DVD could store about 5GB... That was large enough to store a compressed movie in SD. Remember DVDs existed at the same time of the birth of the internet yet DVD was preferred because downloading 5GB was not practical back then... it was more convenient to go to the store and buy a disc. But something VERY important to understand is that the quality of a movie was GREATLY effected by the Variable Bit compression of the media.... there is a profession called a compressionist who artfully adjusts many parameters (mainly the Variable bit rate) in order to create the highest quality movie experience that can fit in 5GB... Blu-Ray was introduced and at a minimum a Blu-Ray disc could store 50GB (and Blu-Ray is actually where the layering technology was introduced allowing up to 4 layers so that a Blu-Ray disc could get as large as 200GB.). Blu-Ray was large enough to compress HD (High Definition) and later 4k & HDR. incidentally can you guess what Blu-Ray's secret sauce is? its in the name! Blue lasers have a smaller light wave that DVDs red laser and therefore more data could be stored in the same sized media. Now, you might think "Why not create a Gamma Ray disc! The wavelengths are even smaller!" That is true but getting a small nuclear explosion needed to generate gamma rays inside a consumer device turned out to be too challenging.... (ok, i'm joking about gamma ray discs) The thing is people prefer Download to own for its convenience. Instead of going to the store and buying a disc, People prefer to watch the same movie online which will be delivered in a handful of GB vs a 200GB Blu-Ray because its easier, however, the download to own movies have a smaller bit budget therefore they are far more compressed (even if they brag being 4k and HDR the real measure of quality is a high bit rate in compression and high bit rate equals more bits that has to be downloaded etc.) The other thing is that recording the data (i.e. Burning a disc) has always been a very long process.... hours and hours to burn a 50GB blu-ray... so even though it makes a great archiving product it is just not even close to as convenient as the cloud. I think a movie put on a disc that stored a petabyte would be AMAZING but consumers will not favor it over the convenience of deciding he or she wants to see a movie and then watching that movie 30 seconds later without leaving home. Again, LOVE your content! You have taught me much oh sensei!

(For the ultimate in security by obscurity, who is going to look on a 3.5" floppy for someone's passwords?) It will be interesting if optical memory makes a come back, though; a bit like how magnetic tape did for a while.

@@jam99 Me: I would be the person who sees someones stack of floppy drives and goes "They probably put some important files on that". If you want security, a password manager, and a means of securing everything: Set up a raspberri pi or similar, with a USB connection to your PC that acts as a Keyboard input. What you want is a small program that will, on request, type in the relevant password after you hit a confirmation button (a physical button on the pi). For real fun security - have several books or such as text files on the pi, and have a program pull up the relevant file, and per algorithm enter the words and do replacements based on said algorithm. The way you secure that algorithm is using a physical device you plug into the raspberri pi - and of course, you can always have a physically printed back up put somewhere secure; to the untrained eye it will look like a math formula. No formula, no password - and since you could conceivably back most of this stuff up in plane text the secret sauce to getting your password is all you need. And because of transformations - brute forcing the password is impractical at best.

Hi. I used to rely on DVDs as my storage for a while. There were some problems with that. Firstly, when they appeared, burning (writing to) to them could fail, destroying the disk. Also, while you could write several times, filling the disc gradually, it took quite a while for each operation, so I did that maybe 2 times. You did have re-writable discs, but most were one write only, so any modification (like removing a picture from a catalog) was impossible (the many-use ones cost about 5 times more and could also fail). So, if you had some data that you wanted to keep and access only rarely, or that you just wanted to backup, they were fine. Still, in time, some could degrade and this was the main reason I witched to other media eventually. I look to this new (or new/old) technology with hope, but I wonder if the issues suffered by the DVDs wont be even more pronounced here.

Before large capacity HDDs became affordable, many companies needing GB/TB of online storage turned to CD jukeboxes as a practical solution, normally paired with smaller HDDs used as cache devices. These would allow several items of required data to be loaded and copied off disk X to the cache before the robot stored X and retrieved/loaded disk Y, which would be accessed in a similar fashion. 📼 This „Swap in/swap out“ methodology has been used for decades. Whether the media is punched cards, floppy disks, CD/DVD-ROMs, HDDs or Ultrium cartridges, the handling of high-latency, large capacity media can always be approached using well understood techniques. 👍

This type of technology was available 20 years ago. It never became commercially available because they wanted to exhaust the market for standard DVDs first, and the prices wanted would be prohibitive. But then the trend shifted back to hard drive storage because of their increased capacity, portability, affordability and perceived better security. They were talking about having the entire Star Trek franchise on one disk, and even greater technology was in the works before it was abandoned. Oddly enough the old CD/DVDs if looked after would well outlast the hard drives and SSD of today. Modern PCs don't even have players for them but if you have an old portable maybe you can.

The gameplay could be fit into that size and scale still for the most part. What you won't fit in is the hundreds of unique textures, the detail of textures, models, and so on. Basically: As Storage became more abundant, computational power grew exponentially, video games took advantage. This is why for years (basically 90's through till around 2014ish) games visual quality got remarkably better every single year. Realism got better - but if we look back now, every "realistic game" that was incredible for it's time is... dated, like severely. The games that have stood up in their visual look are those that went with a visual style that reflected the limits and capabilities of the time and pushed those to the limit. So yes - what have gotten bigger are the art assets - audio, and visual. In truth, most modern "Ultra" settings are just a "Lets roast the computer without gaining any real benefit of note". Where as, in the past, the Original Crisis game was literally a pushed to the limits showcase of the CryEngine and, ya, if you didn't have a top end system of the day: Forget it. It's why the entire meme around "will it run crisis" emerged because if a computer could run crisis decently, it was a really good system of the day. What a fair number of people have kind of clued into now though, is - a good art style, that will run on the modern toaster equivalent of the past, is actually a far better way to go. For one - a good art style will stand the test of time better, but - and this is key - you can reach a wider audience. If you think about Controller + Mouse and Keyboard when you design the game as well, you can create a really good experience with the user selecting how they play the game to their preference - and that means both console and PC release simultaneously becomes more common. Add in control customization by default and - accessibility becomes better.

At about 1:30. Commercial CDs were actually discs of aluminium mechanically stamped with all the holes representing the binary data in one go. They were only read using a laser. CD-Rs and CD-RWs were read and written (and erased if possible) using lasers, here the medium is a kind of ink I believe. Also, the description of Flash drives at 1:55 isn't right. Information isn't stored in magnetisable cells; instead it's stored as electrons across a transistor's PN junction. Applying a reverse polarity overcurrent causes the electrons to 'permanently' tunnel across the junction causing the transistor to read a 0, but the electrons can be forced to tunnel back using an even higher, current a limited number of times causing the transistors to read 1 again. Modern flash uses multi-level transistor currents for higher density storage, but the principle remains. In any case, it's not magnetic.

The problem for me is not the amount of storage in a medium, it is the lentgh of time the medium can reliably store the information. Any regular optical disc for storage (different from commercial audio or video discs) uses dyes that deteriorate over time, somewhere between 10 - 20 years, the same is true for harddisc drives, and it gets worse for thumbdrives, or even tape storage that uses magnetism (LTO) to write the information. I therefore switched for any photography, family research, document storage that need to last beyond my lifetime (especially for genealogy) to M-disc, that like the commercially produced entertainment discs burn a physical deformation (pit) into the information layer.

@@Alondro77 That might be true, depending on the qualities of the dye and the protective layers. I have somewhat differnt ecperiences with write only disc, many of those uplayable now after only 10 or 15 years. Write only discs use changes in reflectivity of the dye layer, which I guess can deteriorate through environmental influences. M-disc however acyually change the surface of the "inorganic layer" by producing pits, similar to a commercially produced CD or DVD. The difference is in the inorganic layer the pits are burned into..some users refer to it to writing in stone. You need a burner with a stronger laser that can write the info that physically deforms this layer. reading can be done by any cd/DVD, Blu-ray reader. I use 50 GB blu-ray M-discs for finisched projects, and 25 GB for projects in progress that i add the info to on a daily basis.

Just as an FYI, Blu-Ray is the current optical storage standard; one needn’t look back to DVDs. Also, the spelling “disk” refers to mechanical-/physical-based data encoding/retrieval, while “disc” refers to wave-privileged media, such as optical discs (as spelled on the IEEE standard logo for the “Compact Disc”).

Dear @Sabine (In the interest of clarity) the CDS/DVDs didn't die because they were superseded by HDs (HDs were there already.. and they always had more capacity than CD/DVDs). CD/DVDs were media storage external to the PCs, and in that sense they were replaced by flash-drives, (or pen drives, or whatever people call them in their respective countries). And (OMG... this one was worse...) a bit is not the same as a byte. A byte is an arrangement of 8 bits.

"and [HDs] always had more capacity than CD/DVDs" weeeelllllll, not "always". When data CDs were first released in 1986 their 650MB size dwarfed the 10 to 20MB hard drive sizes of the day. CD-R came out in 1988 when hard drives were about 40 to 64 MB. It wasn't until about 1995 that computer hard disks passed the 650MB mark. So for about the first decade CDs were bigger than hard disks. And Sabine knows full well the difference between a bit and a byte. You didn't listen carefully to what she said.

Tape storage has made somewhat of a comeback for cold storage sites. I think if they managed to get even in the high TB of data on disks and it was somewhat fast read and write, there would be interesting impacts to backup sites as well. But I think disk media needs to pick back up. Physical media entertainment is slightly more of a hassle but it has its cathartic moments as well. Having the special feature, bloopers, and games on a disc was sort of special. Heck we even bright back VHS tapes so that we can play movies for our kids and have a hard stopping point rather than a streaming service where either it keeps going or you have a title screen stay on. Plus the commercials are so 90s and I love the nostalgia. And if you play them enough your kids inherit some of that nostalgia

CD's stored well are going to hold data just fine. But the cost compared to a Tape Drive is astronomical. And since we already have the infrastructure for secure long term storage of magnetic media - the investment into storing CD's and validating the data etc just isn't worth the investment cost. And for data you are going to use semi-frequently, a pair of data servers with Raid storage arrays validating each-other periodically is so far above what the minimum requirement of most cases is - but is stupidly affordable these days, that you can basically set it and forget it. CD Back up just doesn't really make sense. Even if a company were to produce an archival grade set of disks. Same kind of issue 3D-XPoint as a Memory technology had: It's really cool, potentially really efficient, consumer friendly in many ways but... For bulk scale it's too expensive, for speed it's too slow, and for consumers it's just not practical: In other words, it just doesn't have a big enough market; at least for now - improvements in the technology could very well see Resistive memory become faster and more stable, and if they can get the cost of manufacturing to come down far enough it would likely prove more reliable than Magnetic tape.
