Holes seems to be a computer thing.
Our Apex DVD player and Sharp VHS both have them.
I'm very surprised that the VHS system does. The tape tends to get wound
around the drive head in some Byzantine fashion and manually ejecting
the cartridge while the tape is still wound around is certain to cause a
whole host of problems, likely only resolveable by opening the case
itself.
Well..., the tape doesn't actually "get wound around" anything. As it's
inserted, the protective cover gets flipped up out of the way as the
cartridge descends over /fingers/ that get positioned behind the tape.
(Also, the spindle ratchet locks are disengaged.) The fingers then pull
the tape out and not even halfway around the big round cylinder with the
video heads. (The audio head and the erase head are also moved against
the tape at this time.) When you eject the tape, all that happens is
the cartridge spindles pull the tape back in as the fingers move back to
their home positions. The manual eject mechanism just would (probably)
not pull the tape back in so it might get a little crinkled when the
cartridge protective cover and the VCR dust door close down on the tape
as the cartridge exits. This is from slightly dusty memory, and I was
never a VCR tech. But I had enough interest (when tapes were being
eaten despite normal cleaning) to remove the cover, watch the process,
and try to figure out how to fix the problem.
