C
C
The degree Celsius (°C) is a unit of temperature.
Cache
Specialized RAM used as a buffer between a fast CPU or I/O
channel and storage which has a relatively slow access time (for
example, cartridge or diskette), to avoid slowing down the
former.
Cartridge
Tape cartridge. Super DLT tape II or SDLTtape 600A.
Cartridge Receiver
At media insertion, the cartridge receiver assembly is
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.
CE
Council of Europe.
CFR
Code of Federal Regulations (United States).
Client
This could be a standard FTP client or the built-in FTP client
embedded in the SDLT 600A firmware.
CSA
Canadian Standards Association, also known as CSA
International.
CTM
Cartridge Tape Module. The main function of the CTM is to
provide the magnetic recording media used by the tape drive to
store customer information. The CTM also provides the
protective cartridge, which allows the media to be removed and
stored safely.
CUP
Code Update (a firmware update).
D
Data Compression
A process that reduces the amount of storage space
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.
dB
A Decibel is a logarithmic unit of sound intensity; 10 times the
logarithm of the ratio of the sound intensity to some reference
intensity.
DC
Direct Current
is the continuous flow of electricity through a
conductor such as a wire from high to low potential.
