[ENG] Betamax | Early digital tape recordings on PCM/ U-matic and Betamax video tape : We are now used to living in a born-digital environment, but the transition from analogue to digital technologies did not happen overnight. In the late 1970s, early digital audio recordings were made possible by a hybrid analogue/digital system. It was composed by the humble transport and recording mechanisms of the video tape machine, and a not so humble PCM (pulse-code-modulation) digital processor. Together they created the first two-channel stereo digital recording system. | SOURCE : GREATBEAR audio & video digitising. Early digital tape recordings on PCM/ U-matic and Betamax video tape.

[ENG] Betamax | PCM digital audio recordings on Betamax, VHS or U-matic video tape : ... Developed in the late 1970s, PCM (pulse code modulation) digital audio harnessed the larger bandwidth of video tape technology to digitally encode an audio signal to magnetic tape. PCM digital audio was widely used for studio mastering until the introduction of Digital Audio Tape (DAT) in 1987. | At Greatbear, we carefully restore and migrate to digital files all variations of PCM audio recorded on Betamax, VHS, U-matic or other video tape. | SOURCE : GREATBEAR audio & video digitising.
