Do you assume the problem with RA60 disk packs to be more problematic
because of a smaller availability of systems with RA60 drives to read the
packs compared to CDC 9762 /RM03 drives?
Yes, and the higher density, and the fact that the on-disk format is more
complex and unlikely to be documented in any open documentation.
