Digital Tape Format (DTF) (1994 – 2004) | Museum of Obsolete Media (original) (raw)
Digital Tape Format (DTF) was a magnetic tape cassette format for data storage, and was introduced by Sony in 1994.
Two sizes were available, both using ½-inch metal-particle tape. The S (small) size was based on the Betacam cassette form factor and could hold 12 GB. The L (large) size was based on the larger Betacam cassette form factor that was first introduced with Betacam SP, and was initially able to hold 60 GB.
A second generation, DTF2, was introduced in 1999, and was able to hold 60 GB or 200 GB in the small or large cassettes respectively.
DTF was used for data storage in enterprise computing, as well as for video archiving and recording of seismic data.
It was superseded by formats such as LTO and SAIT, and was given end of life status in 2004, with support until 2011.
