number of components that interact to perform these functions. These
components include:
• Advanced head guide assembly
• Take-up reel
•Drive motor
• Optical servo system
• Tape heads.
In addition to its mechanical components, the DCM also contains printed
circuit boards that control the functions of the DCM and the tape heads.
Tape Control Module 1 The Tape Control Module (TCM) implements the functions required to
buckle and unbuckle the tape and control the tape motion. The TCM
consists of a variety of components:
• TCM Printed Circuit Board Assembly (PCBA)
• Base Plate
• Data Cartridge Receiver
• Positive Engagement Tape Leader Buckling Mechanism
• Tape supply motor assembly
• Floor plate assembly.
TCM PCBA
1
The TCM has its own PCBA that controls the functions of the TCM and
interfaces with the main controller board in the EIM. By designing the
TCM as a distinct module, it allows manufacturing and testing the TCM
as a stand-alone module, simplifying the design, manufacturing, and
troubleshooting processes.
Base Plate
1
The SDLT 600A tape drive base plate is an aluminum die casting with
precisely machined surfaces. The casting acts as the support platform for
the other modules and for the tape drive enclosure. The base plate also
includes the precision mounting holes used to install SDLT 600A tape
