Actually, I thought that what's promoted as a bigger advantage of flying
erase heads is that when you stop recording, there's no erased section
after the newly recorded part.  That way, you can stop recording at a
precise point and whatever you were recording over will continue right away.

ObHack:  Getting the same effect with a regular VCR.  I noticed that one
of the heads could be easily moved away from the tape when it was
recording, and this happened to be the erase head.  If you hold it away
>from  the tape while recording, it won't erase anything ahead of the
current record position, so when you stop recording there's a clean break
to whatever was there before.  The drawback, of course, is that anything
that's recorded without the erase head clearing the path first has some
extra "effects" to it, like the noise you get when you first start
recording something (since the erase head hadn't gotten to that yet either).
