Data Interchange on 12,7 mm 128-Track
Magnetic Tape Cartridge - Parallel Serpentine Format
2nd edition (June 2000)
This Ecma Standard specifies the physical and magnetic characteristics
of a magnetic tape cartridge, using a magnetic tape 12,7 mm
wide, so as to provide physical interchange of such cartridges
between drives. It also specifies the quality of the recorded
signals, the recording method and the recorded format known as
Parallel Serpentine, thereby allowing data interchange between
drives by means of such cartridges. The format supports variable
length Logical Records, high speed search, and the use of the
algorithm for data compression specified in Standard.
Information interchange between systems also requires, at a minimum,
agreement between the interchange parties upon the interchange
code(s) and the specification of the structure and labelling of
the information on the interchanged cartridge.
Together with a standard for volume and file structure, e.g.
Standard ECMA-13, this Ecma Standard
provides for full data interchange between data processing systems.
