That can happen if the end-of-tape light has died in the VCR,
in which case it will happen again. Try it with a VCR which
doesn't matter.
Thanks for the suggestions.
The tape has definitely pulled out of the cassette centre spindle - I
can see the empty spindle in there and it happened when the tape was
had rewound to the beginning. I heard the clunk as the rewind
finished.
I was wondering how tricky it is to disassemble/reassemble the
cassette itself. If I can just get it to play one time mo-)


This is something I must have done scores of times.
If the transparent leader has snapped or pulled out of the
take-up (RH) reel then it's very easy. No splicing as such required.

Remove any label on the back of the cassette, or slit it with a sharp
knife
Remove the 5 screws from the bottom and carefully turn it over
so it's the right way round
now very carefully lift the top clear, make sure the steel pins
and roller guides remain in their holes in the lower
half. Try not to disturb the flap in the lid, there is a small hairpin
spring that keeps the flap closed.

It will do no harm at this stage to take a picture.

remove both reel from the cassette whilst holding the sprung ratchet
do it doesn't fly off and get lost.
slide out the little quadrant shaped clip that secures the tape to
the hub. I bet you find a small piece of transparent leader in
there. the tape rarely pulls clean out.
Now unwind enough tape from the supply-spool to work
with and allow the end of the leader to lie over the gap
in the hub with about 4mm overhang
don't slide the clip in that wont work, you need to clip
it in bodily, trapping the leader. You need a strong finger but it will
go in.
Now return the spools to the cassette, carefully engaging the
teeth with the ratchet.
The tape goes between the large and small guides;
ASCII art isn't my strong point.

Take up the slack and carefully drop the lid on.

Other have made a passing mention - but - be aware that the transparent
section is there to operate the sensor to brake the rewind action.


Yes.
Early VHS machines used a incandescent bulb as the light source.
This needed replacing several times during the lifetime of the
machine.
Later machines use an IR LED.
