Title
Information Systems - Unrecorded Magnetic Tape Cartridge for Information Interchange - 0.250 Inch (6.30 mm), 1600 bpi (63 bpmm), Phase Encoded
American National Standards Institute
Publication Date:
Jun 17, 1992
Scope:
This standard, for an unrecorded cartridge containing 0.250 in (6.30
mm) magnetic tape, presents
the minimum requirements for the mechanical and magnetic
interchangeability of the cartridge
between information processing systems, communication systems, and
associated equipment utilizing a
standard code for information interchange, as agreed upon by
interchange parties. This standard
refers solely to the magnetic tape and cartridge with various lengths
of tape for digital
recording, and complements American National Standard Recorded
Magnetic Tape Cartridge for
Information Interchange, 4 Track, 0.250 in (6.30 mm), 1600 bpi (63
bpmm), Phase Encoded, ANSI
X3.56-1977.
The magnetic tape cartridge consists of two coplanar hubs loaded with
0.250 in (6.30 mm) wide
magnetic tape (see figure 1). The tape is transported between hubs by
an internal belt which is
coupled by an internal belt capstan to the external drive. No
tape-driving or position-sensing
elements penetrate the cartridge.
This standard applies to cartridges used for data interchange. Where
it applies to cartridge
testing only, it is specifically stated.
CAUTION NOTICE - The user's attention is called to the possibility
that compliance with this
standard may require use of an invention covered by patent rights. By

any patent rights in
connection therewith. The patent holder has, however, filed a
statement of willingness to grant a
