How do you figure that?  I've got a DC600HC cart here and it's the same
dimensions as a standard DC600A cartridge--it is Iotamat preformatted,
without the usual optical sense stuff.   It was used on a number of QIC
(yes, it's quarter-inch) drives, such as the Kennedy 9455 and the ADIC
32-track drives.

As far as the capstan being too large, I suspect you may underestimate
the "stretchiness" of silicone hose.   Somewhere, I posted a photo if an
Archive 2060S drive with a red hose replacement capstan.

The hose comes in larger sizes, regardless.   I still need to refurb the
capstan on my 3M DCD-01 drive, but it's been too long since I've run
into any 2-track DC300 tapes, so it's not a priority.

In any case, the suggestion is offered for whatever value one can gain
from it.
