Well, I think those cartridges use wider tape and something like the
"helical scan" used on VCRs, so the track is a series of diagoinal
stripes laide down by a spinning head, set at an angle to the tape.
That way the speed of the tape past the *head* is faster than the speed
thru the tape transport rollers.

When I was a kid we had one of those old wind up record players for
quite a few years.
