Yes. On every
DEC drive I own (and I guess most others), track 0 is at
the outside edge of the disk and the highest track is closest to the
spindle. Allison/Tim will now post a list of exceptions :-)
Only exception I know of is CD-ROM, which doesn't exactly have tracks,
but at least block 0 is on the inside and the higher-number blocks
are on the outside.
I seem to remember something about the RD series disks (or at least the
RD52 or RD53) installed in a PRO-series machine having the outermost
track *not* track zero...
