Digital cassettes explained
Digital audio cassette formats introduced to the professional audio and consumer markets:
Digital videocassettes include:
Analog cassettes used as digital data storage
- Historically, the compact audio cassette which was originally designed for analog storage of music was used as an alternative to disk drives in the late 1970s and early 1980s to provide data storage for home computers.
- The ADAT system uses Super VHS tapes to record 8 synchronized digital audiotracks at once.
- There have also been several audio recording systems which used VHS video recorders as storage devices and video tape transports, generally by encoding the digital data to be recorded into an analog composite video signal (which resembles static) and then recording this to magnetic tape. These systems were generally used as "mixdown" recorders, to record the finished mix from a multi-track recorder in preparation for the manufacture of a vinyl record, cassette tape, or CD. An example was the Dbx Model 700.[1] Another example is the Sony PCM adaptor series.
- Several companies sold VHS backup solutions in the 80s and 90s where data was converted to a video image which was then saved on a VHS tape.
- the Corvus "Mirror"
- the Metrum Model 64 on S-VHS tape,[2]
- the Danmere Backer tape backup system,[3] [4]
- the Alpha Microsystems Videotrax[5]
- the Legacy Storage Systems International VAST (Variable Array Storage)[6]
- the ArVid
- the Video Backup System Amiga,[7] [8]
- The S2 VLBI system at three NASA Deep Space Network complexes and over 20 other radio telescopes stores digital data on SVHS tapes.[9]
