Because I want it to be as generic as possible. If it is possible to move
the heads I can read tapes that are written not only by a TU58 but also on
a any DC100 compatible device. I dont know what sort of head HP made use
of for their HP9825 and HP2645 for example.
I here compare what AJ have done with a Wangtek 5099 drive. Being able to
read a tape written by a completely different drive (DEI) by just
positionig the head correctly. The resulting data I then decoded in
software and the original tar archive was recovered. Now the encoding was
MFM in th S8000 not GCR which was used normally by the QIC-02 and SCSI
drives with nine tracks and DC300.
