I am trying to get TRUE and COMPLETE information on function of
number of video heads in a VCR.  The best theory I heard so far
is that one set of heads (2) has optimized head gap for Standard
Play (SP) mode and the second set of heads (2) has optimized head gap
for Extended/Long Play (EP/LP) and Super Extended/Long Play (SEP/SLP).
I would like to know if that is TRUE?  If NOT, then how are the four (4)
or three (3) or five (5) heads used?  If YES, then how do the three (3)
and five (5) head machines work? Please post to the net for general
audience information.  Thanks in advance.
