Rev AUG-01-76
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 of 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 Read/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.
