you'll need some tape driver. The only software I know of for this purpose is
GEMAR from Steffen Engel. At least the actual version is still quite buggy and
does not seem to be supported any more (at least I didn't see any corrected
version for the last 1-2 years). The parts that causes a lot of trouble are:
1. The driver code itself
2. The GEM interface

The driver is said to set upon the SCSI interface but at least on my machine it
seems not to be the case. So on my PAK'd MEGA GEMAR will hang quite often with
caches activated. The GEM interface complains on not enough memory every time
I'd try to restore a tape.

These severe problems are the reason why I did not register GEMAR nor using it
on a regular basis.

There are at least two ways to use the tape: the xfs mode and the tape mode.
Even though the xfs mode (which is normally used together with the GEM 
interface) is quite unuseable at least the tape mode works if you turn all
caches off.
