6.2 Handling 8 mm magnetic tape cartridges
In order to achieve the best possible recording quality, it is recommended that
the magnetic tape cartridges supplied by your local office are used (see the
chapter “Accessories” on page 87). These cartridges are precisely matched to
the characteristics of the drive.
V Use exclusively magnetic tape cartridges approved by Fujitsu Siemens
Computers and the manufacturer Exabyte
®
in the 8 mm MTC drive.
Other magnetic tape cartridges can damage the MTC drive. Never use
Video 8 cartridges.
The following magnetic tape cartridges are recommended:
Magnetic tape cartridges can be ordered directly by calling your local office (see
the chapter “Accessories” on page 87).
6.2.1 Life of a magnetic tape cartridge
The life of a cartridge depends on the frequency with which the tape passes the
read/write head. The number of “head passes” is proportional to the quantity of
data transferred.
The following applies to 8 mm cartridges.
A maximum of 1500 head passes can be performed.
One backup requires three passes of the tape, since the tape is deleted, written
and then rewound. This means that approx. 500 backup operations are
possible.
If, however, each of these backups is read once, the life of an 8 mm cartridge is
reduced to approx. 250 backup runs.
If the MTC drive is working in start/stop mode, i.e. if the tape is regularly stopped
and the read/write head continues to revolve, the life of the cartridges is reduced
dramatically.
