DAT
Digital Audio Tape.
DDS DDS (Digital Data Storage) is the original industry-
standard data interchange recording format that supports
the use of DAT for computer applications. The DDS
format is an overlay to the basic DAT audio format.
Under DDS, fixed capacity data groups are constructed
on tape with pairs of tracks (or frames) from the audio
format.
DDS-3 DDS-3 is an industry-standard data interchange
recording format built on the strengths of the DDS
format, combined with increased performance. The DDS-
3 format allows writing of compressed entities and
uncompressed records on the same tape. The DDS-3
format is written to MP+ media only, presently available
exclusively in 125-meter data cassettes.
DDS-3 cassette
Media used with the DDS-3 DAT tape drive in the VLS
4mm unit. It is a data-quality 4mm metal-particle
cassette. These cassettes require no formatting or other
media conditioning before use.
