down to 2.3 Gbyte mode.
Cartridges with a capacity of 7 Gbytes (160m) can only be used in an

may only use cartridges with a capacity of 20 Gbytes (170m). If in doubt,
please contact your local Siemens Nixdorf office.
To obtain optimum recording quality you are advised to use the cartridges available

racteristics of the drive.

!

The service life of a tape cartridge depends on how often the tape is read and written
and how the cartridge is handled.
Quarter-inch cartridges can be read about 260 times or read and written 130
times.
4 mm and 8 mm cartridges can be read about 500 times or read and written
250 times.
After this number of operations a cartridge is worn out and should no longer be used.
