3,81 mm Wide Magnetic Tape Cartridge
for Information Interchange - Helical Scan Recording - DDS-4 Format
This Ecma Standard specifies the physical and magnetic characteristics
of a 3,81 mm wide magnetic tape cartridge to enable physical interchangeability
of such cartridges between drives. It also specifies the quality
of the recorded signals, the recording method and the recorded
format - called Digital Data Storage 4 (DDS-4) - thereby allowing
data interchange between drives by means of such magnetic tape
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
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.
