Really?  DC300 = quarter-inch tape, 300 feet, written by lots of
"QIC" 4 and 9 track drives in serpentine fashion, including the IBM
6157.  My old 3M catalog lists it as a quarter-inch tape.  I've got
one here; fits in a standard-sized QIC drive and works like any other
QIC cart (e.g. DC600A).
Maybe we're caught in a Python sketch:
"Cole Porter ... who wrote `Kiss Me Kate'?"
"No, alas not, sir ... this was Cole Porter who wrote `Anything
Goes'".
