Thanks for proving my point that logically and physically there are two
heads,
not one. That the heads can read and write at the same time and read after
write
would be possible *IF* there were to be seperate Read and Write channels,
(which there aren't).
Ron Rough made the impression that is was impossible because there is only
one head. That point is false. It's because there is only one R/W channel.

That's false the magnetics and physical proximity precludes both being
active simultaneously.
