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
drives into a server or tape library. The SDLT 600A tape drive base plate,
and therefore the entire SDLT 600A tape drive, conforms to the 5.25 inch,
full-height form factor.
Data Cartridge Receiver 1
On tape insertion, the data cartridge receiver assembly guides the tape
into its operating position, opens the data cartridge door, unlocks the
data cartridge brakes, engages the data cartridge drive motor, and
secures the tape for operation. On tape ejection, the data cartridge
receiver assembly reverses the process and automatically ejects the tape a
fixed distance from the front of the tape drive.
Positive Engagement Tape Leader Buckling Mechanism 1
The buckling mechanism is responsible for engaging the tape leader upon
data cartridge load and disengaging it on data cartridge unload. See
Positive Engagement Tape Leader Buckling Mechanism on page 29 for
more information.
Front Panel Module 1
The Front Panel Module (FPM) of the system (sometimes referred to as
the bezel) performs a number of functions:
• Protecting the front of the TCM from physical damage
• Channeling airflow through the system
• Aligning the data cartridge when it is inserted into the system
• Providing system status and information through LEDs
• Enabling data cartridge ejection
