M MB Megabyte. A unit of measurement equal to 1 million bytes.
MCBF Mean Cycles Between Failures. This is average cycle count
between possible failures. A cycle is the movement of a
cartridge from the tape drive to a magazine slot and the
selection of another cartridge and moving that cartridge back to
the drive.
MHz MegaHertz. A measurement of frequency in millions of cycles
per second.
MTBF Mean Time Between Failures. Reliability rating indicating the
expected failure rate of a product in power on hours (POH).
Since manufacturers differ in the ways they determine the MTBF,
comparisons of products should always take into account the
MTBF calculation method.
MTTR Mean Time to Repair. The average time it takes to repair a drive
that has failed for some reason. This only takes into
consideration the changing of the major subassemblies such as
the printed circuit board or sealed housing. Component-level
repair is not included in this number as this type of repair
cannot be performed in the field.
media The material or device used to store information in a storage
subsystem, such as a tape or disk drive. DLTtape media is a high-
grade metal particle (MP) formulation that takes advantage of
the latest advances in binder chemistry. By combining both solid
and liquid lubricants in the tape binder system, tape and head
wear are reduced while repelling airborne particles that could
affect read/write head performance. In addition, by using a
uniform particle shape, a dense binding system, a smooth
coating surface, and a specially selected base file, Quantum
DLTtape half-inch cartridge tapes take advantage of shorter
wavelength recording schemes to ensure read compatibility
with future generations of DLT drives.
Metal Particle (MP) tape A magnetic recording media in which a
flexible base is coated with a mixture of magnetic particles and
a bonding agent. See also media.
microprocessor The integrated circuit chip that performs the bulk of
data processing and controls the operation of all of the parts of
the system.
microsecond (μs) One millionth of a second (.000001 sec.).
