BS ISO/IEC 13421:1993

This standard BS ISO/IEC 13421:1993 Information technology. Data interchange on 12,7 mm, 48-track magnetic tape cartridges. DLT 1 format is classified in these ICS categories:

• 35.220.23 Cassettes and cartridges for magnetic tapes

This International Standard specifies the physical and magnetic characteristics of a 12,7 mm wide, 48-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 1 (DLT 1) - and a recording method. Together with a labelling standard, e.g. ISO 1001, it allows full data interchange by means of such magnetic tape cartridges.
