Defines the physical and magnetic characteristics of a 12.7 mm wide, 112-track magnetic tape cartridge, enabling interchangeability of such cartridges. In addition, it defines the quality of recorded signals, a format and a recording method. Gives full data interchange by means of such cartridges.

This International Standard specifies the physical and magnetic characteristics of a 12,7mm wide, 112-track magnetic tape cartridge, to enable interchangeability of such cartridges. It also specifies the quality of the recorded signals, a format - called Digital Linear Tape 2 (DLT 2) - and a recording method. Together with a labelling standard, e.g. ISO1001, it allows full data interchange by means of such magnetic tape cartridges.
