4mm DAT/DDS, DDS1, DDS2, DDS3, DDS4 & DAT72 tape cataloging / indexing / backup listing

4mm DAT DDS:

The Digital Data Storage (DDS) magnetic tape data storage format was developed by Sony and Hewlett Packard in 1989 as an evolution of Digital Audio Tape (DAT). The tape medium itself is nominally 4mm (actually 3.8mm) wide, packaged in a compact plastic cartridge containing dual reels, and was originally 60 or 90 meters long.

Initial native (uncompressed) capacity was 1.3GB on a 60 meter tape, and 2GB on 90 meter tapes. 1993 saw the release of the DDS-2 standard, with a native capacity of 4GB on 120m tape, and the later DDS-3, DDS-4 and DAT-72 generations held 12GB, 20GB, and 36GB respectively. Hardware Compression enabled tapes to typically double their native capacity.
