[net.video] cleaning vtr heads

VTR video tape heads are EXTREMELY delicate and easily damaged by improper
cleaning.  It is very important that non-abrasive materials be used
for cleaning, that no residue be left on the heads, and that the motion
of cleaning (for helical-scan VTR's) always be VERTICAL ... never horizontal.
Violating any of these "rules" can ruin video heads in short order -- they
are incredibly more delicate than normal audio heads.

In general, it's simply safer to leave video heads alone until you MUST
clean them.  I have one old Beta machine here that I've used heavily for 
almost 5 years -- I still haven't had to clean the heads.  It certainly
helps if you don't use "cheap" videotapes -- some brands leave residue
on the heads even after the first use.

Although vortex!lauren says that cleaning VCR heads
should be done with a vertical motion, one reference
book I've seen (don't remember the title), as well
as the directions that came with the little bottle
of cleaning fluid I purchased, said *horizontal* motion
only! Anyone have a definitive (& correct) answer?
