enclosure. The base plate is standard 5.25 inch (133.35 mm) full-
high form factor and includes the precision mounting holds used
to install Super DLTtape drives into a server or tape library. The
TCM acts as the prime base plate for the Super DLTtape system.

freezing and 100 degrees is the boiling point of water.
At tape insertion, the cartridge receiver assembly is
cartridge receiver
responsible for guiding the tape into its operating position,
opening its door, unlocking the cartridge brakes, and securing
the tape for operation. At tape ejection, the cartridge receiver
assembly reverses the process and automatically ejects the tape a
fixed distance from the front of the drive.
compressed capacity
storage space while maintaining data integrity using either
software or hardware.
cartridge tape module (CPTM)
AMP media feature of Quantum's LGMR technology. The main
function of the CTM is to provide the magnetic recording media
used by the drive to store customer information. The CTM also
provides the protective cartridge that allows the media to be
removed and stored safely.
A process that reduces the amount of storage space
data compression
required to hold a particular block of data. Data transfer speed
and total tape capacity are affected by the data compression
achieved. In accordance with industry practice, a typical
compression ratio is 2:1 of data storage. Actual compression
ratios achieved are dependent on the redundancy of data files
being recorded.
data control module (DCM)
and features of Quantum's LGMR technology, which is at the
heart of the Super DLTtape technology. Of the five technologies
that constitute the LGMR technology, two are found in the DCM.
These are the POS and the MRC heads. The main functions of the
DCM are to provide the path and guides for all tape motion
inside the drive and to write data to and read data from the tape.
