3 4 mm MTC drives (DAT)

The 4 mm MTC drive allows you to read and write to 4 mm magnetic tape

cartridges. The format of these cartridges derives originally from the field of

entertainment electronics, which also gave them the name DAT (Digital Audio

Tape). However, since the requirements with regard to reliability are higher

when a tape is used for recording data than when it is used for recording music,

it is necessary to use special magnetic tape cartridges (see also the section

“Handling 4 mm magnetic tape cartridges”).

Up to 12 Gbytes of data can be stored on a 4 mm magnetic tape cartridge with

a length of 120 m if no compression is used. This MTC drive also allows data

compression, so that, depending on the type of data, between 8 and 24 Gbytes

of data can be recorded.
