3,81 mm Wide Magnetic Tape Cartridge
for Information Interchange - Helical Scan Recording - DDS-2 Format
using 120 m Length Tapes
2nd edition (June 1995)
This Ecma Standard specifies the physical and magnetic characteristics
of a 3,81 mm wide magnetic tape cartridge to enable interchangeability
of such cartridges between drives. It also specifies the quality
of the recorded signals, the recording method and the recorded
format, thereby allowing data interchange between drives by means
of such magnetic tape cartridges.
Information interchange between systems also requires, at a minimum,
agreement between the interchange parties upon the interchange
code(s) and the specifications of the structure and labelling
of the information on the interchanged cartridge.
Under information interchange circumstances in which a processing
algorithm, e.g. for lossless data compression as specified in
Standard ECMA-151, is applied to the
host data prior to recording on the tape and a complementary reprocessing
algorithm is applied after the data is read from the tape, agreement
upon these by the interchange parties is also required.
