Sony digital camera recorder tapes9/16/2023 ![]() ![]() The 3324 was introduced in 1978 and is actually credited (disputed) with the first ever digitally recorded film score (Star Trek, The Motion Picture). The 3302 was for 2 track mastering, the 3324 was a 24 track recorder and the 3348 a 48 track recorder (which wasn’t launched until 1989 due to technical issues). ![]() So while one team were working on the development and release of the PCM-1/Betamax and eventually the PCM-1600/U-matic, another team were developing a completely different system and it’s this system that Sony took to the table with Philips in 1979 to develop the CD Redbook standard! Also at this time Sony were developing another tape based digital audio recorder, the PCM-33xx series. In other words, to develop a brand new way to directly record the digital audio signal onto an optical disc, instead of using a video signal from a video recording format.” - The 3rd decision was to develop better error correction. The second decision was to approach the audio disc and the videodisc as unrelated items and give priority to developing audio technology. The first was to use the PCM-1, which they had been preparing to launch in the autumn of that year, as an adapter exclusively for Betamax. “ After looking into the causes, Doi made three decisions. ![]() However, the results were poor and in Sony’s OWN words ( Making Digital Audio a Reality - ): At the same time, another team in Sony were working on video laser disk (manufactured by Philips) and as this technology was seen as the future, yet another team of engineers were set the task of trying to pair the PCM-1 with the laser disk to create a digital audio laser disk. What actually happened is Sony introduced the Betamax VCR in 1975 and then in 1976 developed the videotape PCM adapter (PCM-1) to use the Betamax VCR as the digital recorder. Indeed Sony itself followed more than one of those lines and had different teams working on different solutions but you’ve effectively only investigated one (and not the right one!). As I mentioned previously, there were numerous lines of development in digital audio recording in the mid-late 1970’s, only some of which were based on videotape technology. ![]() What you’ve failed to investigate or understand is all the other contributions to the development of the CD standard and therefore that videotape played virtually no role, except as effectively a discarded stepping stone along the way. Apart from U-Matics for transferring masters, there was no videotape technology involved.Ĭlick to expand.It’s evident to you (and only you!) because you’ve only investigated one part of the history, which unsurprisingly appears to be according to your personal agenda of video. Sony also demonstrated a prototype recorder based on reel-to-reel stationary head linear-scan (DASH) technology in 1977, although they didn’t bring it to market until 1982 but along with ProDigi’s reel-reel stationary head recorder they almost completely dominated the professional studio (digital) recording industry for over a decade. Sony developed a videotape based professional audio recorder (U-Matic), which ran at 44.056kHz and is the only videotape format which achieved mainstream professional use but not for recording, it was used exclusively for transferring masters. 3M’s entry to the market also ran at 50kHz (and again was not based on videotape). The most important/influential development was by SoundStream in 1976, because it demonstrated commercial usability, but it was not based on videotape, it was based on a 16 track “instrumentation tape recorder” by Honeywell, originally running at sampling rate of 37kHz but the commercial models a year later ran at a 50kHz sample rate. Denon’s original recorder operated at 37.5kHz and Decca’s at 48kHz for example. Although the first digital recorder was based on videotape and that became a line of development for some companies in the 1970’s, none of those systems operated at 44.1kHz.
