AIT
Advanced Intelligence Tape is a new tape technology developed by Sony. It
incorporates a new recording format, MIC (Memory In Cassette) capabilities,
and uses AME (Advanced Metal Evaporated) media.
A-ME
A-ME (Advanced Metal Evaporated) is the tape formulation used by AIT. Key
characteristics include 100% pure cobalt magnetic layer, dual magnetic layer
design, the absence of binder material to prevent head contamination, and DLC
(Diamond Like Carbon) protective coating for extreme durability.
byte
8 bits of digital data
C
Celsius (Centigrade)
cassette
A storage medium item. A cassette is sometimes called a tape or cartridge and
is capable of storing vast amounts of magnetically written data. Some cassettes
can store more than 50 gigabytes of data.
cleaning cassette
Media used to clean the drive heads and tape path. Use only a Sony SDX-TCL
cleaning cassette in the SDX-300C drive.
cm
centimeter (0.3937 inches)
FCC
Federal Communications Commission
ferrite bead
A device used to suppress radio noise in certain conditions to meet
specifications.
GB
gigabyte (1 GB = 1,024 Megabytes)
HSM
Hierarchical Storage Management – a system where different types of storage
media are used based on cost and time efficiency. For example, for fastest
access, data is usually stored on a local hard drive. If you have a very large file
that is needed occasionally, you may store it on a tape or on an optical drive. In
an HSM system, the data source should be transparent to the user.
HVD
High Voltage Differential. A type of SCSI interface that employs differential
signal lines at high-voltage levels. Also commonly referred to as Differential.
Hz
Hertz (replacement for "cycles-per-second").
initiator
A host computer system that requests an operation to be performed by a target
device.
KB
kilobyte (1 KB = 1,024 bytes)
LCD
Liquid Crystal Display. A commonly used alphanumeric display that responds
to specific input voltages and signals.
LED
Light Emitting Diode, a commonly used semiconductor device that glows when
supplied with a specified voltage.
Loaded
The tape is loaded after the drive has performed identification and verification
tests, positioned the tape at its beginning, and is ready for access commands.
LVD
Low Voltage Differential. A type of Ultra SCSI interface that uses low- voltage
differential signal lines.
MB
megabyte (1 MB = 1,024 Kilobytes)
