Cartridge Tape Module
1.0 IMTRODUCTION.
13255-91032/02
Rev AUG-Ol-76
The cartridge Tape Module consists of a Cartridge Tape Unit (CTU)
Interface peA, a Read/Write PCA, a CIU Top Plane Assembly, two CTU
Transport Assemblies, and one or more mini tape cartridges. Each tape
cartridqe contains 150 teet
~f
single-track O.150-inch tape with
a
maximum tOrmatted storage capacity ot 110K eight-bit data bytes. The
dual cartridge tape units provide full read and write capabilities for
phase-encoded data.
Data,
command, status information, and address
interfacing between this subsection and other terminal modules is pro-
vided by the Backplane Assembly and CTU Interface PCA. The R~ad/Write
PCA controls recording, reading, and tape motion Of the two CTU Trans-
port Assemblies. Interfacing between the two PCA's is provided by the
CTU TOp Plane Assembly and interfacing between the Read/write PCA and
the two CTU Transport Assemblies is provided by a Motor cable Assembly
and two CTU ribbon cable assemblies.
