At media insertion, the cartridge receiver assembly is
Cartridge Receiver
responsible for guiding the media into its operating position, opening the
door, unlocking the cartridge brakes, and securing the media for
operation. At media ejection, the cartridge receiver assembly reverses the
process and automatically ejects the cartridge a fixed distance from the
front of the tape drive.

Data Compression
required to hold a particular block of data. Data transfer speed and total
media 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 depend on the
redundancy of data files being written.
A Decibel is a logarithmic unit of sound intensity; 10 times the
dB
logarithm of the ratio of the sound intensity to some reference intensity.
Direct Current is the continuous flow of electricity through a

conductor such as a wire from high to low potential.
The Data Control Module provides the path and guides for all
DCM
media motion inside the tape drive and to write data to and read data
from the media.
