FWIW the tape drive is an IBM 2315 announced April 16, 1965
<https://www.ibm.com/ibm/history/exhibits/dpd50/dpd50_chronology3.html> for use on
low end S/360s. Here is a brochure

So, is that a capstan and pinch roller drive? I'd kind of
guess so, if announced in 1965.
(for future readers, 2315 is apparently a typo, 2415 would
fit in with 24xx models being tape drives, 23xx was for disks.)
