Digital Data Storage

Digital Data Storage (DDS) is a format for storing computer data derived from Digital Audio Tape (DAT).

DDS uses tape with a width of 3.81mm, with the exception of the latest formats, DAT 160 and DAT 320, which are 8mm wide. Initially, the tape was 60 meters (197 feet) or 90 meters (295 ft.) long. Advancements in materials technology have allowed the length to be increased significantly in successive versions. A DDS tape drive uses helical scanning for recording, the same process used by a video cassette recorder (VCR). If errors are present, the write heads rewrite the data.
