This Ecma Standard specifies the physical and magnetic characteristics of a 12,7 mm wide, 448-track magnetic tape cartridge, to enable physical interchangeability of such cartridges between drives. It also specifies the quality of the recorded signals, a format – called Super Digital Linear Tape 1 (SDLT 1) – and a recording method, thereby allowing data interchange between drives. Together with a labelling standard, for instance Standard ECMA-13 for Magnetic Tape Labelling, it allows full data interchange by means of such magnetic tape cartridges.
