never saw those compressed slots, apart i would like to say that the cd developed in the 70´s could have been substituted for a more quality format what makes a lot of people in this world still listen to vinyl(not this new turntables with a horrible sound and cartridges payed like if it were made doble their weight in gold, the DAT is from the 80´s and why not?it´s not comparable with the poor cd sound as digital ,some would say to record in analog because analog was fully developed and digital would sound poor ,in the cd-r case the optical conection on the first pioneer recorders was equal to the cd ,but only 3 copies but you get another cd and 3 copies more, but two was enough, one for you and might make a copy to a friend,people discuss digital as if the compact disc is the only digital source but some is making a lot of money by still using the cd format ,even in dvd´s or Blue-ray´s. To end ,in 1990 i bought a doble live album from a band called dream syndicate that i really like maybe 5 songs and it had already the cd version but the cost at the time was doble the record and had a few more songs, i was like ,how can this be the best recorded live record i ever had and i have many ,the sound is simple two six string guitars ,a bass ,voice and drums it sounded like i was in the room who was tiny, the raji´s ,in the back cover it said directelly recorded into DAT, i have to say that cds till the 90´s were made of a diferent more expensive material, the reason why the price came down in the 90´s, but later or almost 20 years later i bought an excelent copy of this album in compact disc ,it sounded so horrible that i never played it again but the original recording was made in a DAT recorder, i think one can see the diference is the format being so old and low quality ,i have a lot of cds but i also have what some say it´s the best cd player in the world, it was ofered ,today is still sold by 36.000€ a CEC belt driven cd player ,when i saw the price i couldn´t believe mine was free in the 90´s ,what to say ,i don´t know analog/digital, i use the best of both as i have a studio at home since 1970 improved along the years almost nothing there was what it was assembled in 1970, like a reel tascam 4-track recorder i´m using in my home system

Not only that, when PCM on video tapes and later DAT came out dcc was not even in the scene, it took few years later for Philips to develop the format. DAT was not a new creation, it stemmed from the PCM digital recording on uMatic videotapes, then Beta and VHS videotapes for small studio and home recording, The idea was to create a unique recording system that directly record digital on tape instead of black and white video stripes that represent 0's and 1's on those videotapes.

Köszi!

Köszi szépen!

Hello. Ez a Dual Mono, hogy a jobb és bal sáv két nyelv lehet volt Laserdisc-en is, VHS-en is, sőt ott még az is, hogy a HiFi sáv egy nyelv és a mono sáv egy másik. Volt is ilyenem gyáriba, de már rég eladtam. A Tom és Jerry lemez hangja csak mono és rábeszéltek, nem vitték túlzásba. Üdv

Oh, ezeket nem tudtam. Először VCD-nél botlottam ilyenbe. Köszi az infót, érdekes!@@ChrisFilmDigital

Hi, Thank you! Hope it will not be a problem, I try to find all informations for all systems and use them. Best, Chris

No it's absolutely no problem, I do state on my contact page about contacting me for using my content but it's all fair use. I just like to see other people having the same interest in stuff like this so keep up the good work Chris 😉

Hi, Yes i found that info too, but in theory they convert it to a very high version of PCM... Thank you, I try to be continously dual language, even with delays. Best, Chris

And VHs and Beta.
