Typically, as you step towards higher capacity tape drives, they maintain
the ability to read the lower capacity tapes, but not neccessarily be able
to write to the lower capacity tapes.
The QIC-150 tape drives can usually;

write/read	QIC-150	(150MB, DC-6150, DC-600XTD)
write/read	QIC-120	(120MB, DC-600A)
read		QIC-24	( 60MB, DC-600?)

I don't believe any of them can handle the QIC-02 format, but I could be
wrong here.
