Default How do VCRs recognize the beginnings/ends of tapes?

Anyone know how this works? Is there a sensor that recognizes the
transparent bits at the beginning and the end of a VCR tape?

I have two Sony VCRs that upon rewinding come to a crashing halt
rather than a smooth stop.


VHS VCR's use the transparent tape at each end. Old style VCR's used a light
bulbs and photocell. Newer ones most likley use an LED and some sort of
photosensor. It should not be hard to find, it would be the only part
that the tape goes through instead of over or around.
