<div>Everyone is correct so far. The VR-3000 was making tapes that were
not to standards. We had a local facility that did industrial videos and
used a VR-3000 as a record device. They had the AVR-1 as a playback.
It always worked.</div>
<div> </div>
<div>So what is standard for the control track? I would have to go get a
book and study it a bunch. But here is what we did to compensate for all
the little variances in manufacture of a video head to control track head
spacing.</div>
<div> </div>
<div>When doing an Intersync alignment, we would use the alignment tape as a
playback for centering the tracking control. There were four (?) pots that
would set it for each position of the head selector. This meant that the
machine would play any tape recorded to standard with the tracking knob at 12
o'clock.</div>
<div> </div>
<div>Next would be to record on blank stock using the procedure to put the frame
pulse at the top of the control track 240 Hz sine wave. When playing this
recording back, if the tracking know had to be moved from the 12 o'clock
position, then the recoding was not to the same standard as the alignment
tape. I would then move the frame pulse a bit left or right and then try
again until the tracking knob on playback was straight up. </div>
<div> </div>
<div>This procedure compensated for the minute tolerances in
manufacturing. There is an adjustment on the Mark X heads to move the
control track head but we never considered doing this as it was a chance to do
more damage and a big waste of money. </div>
<div> </div>
<div>Our goal was to create tapes that were as close as possible to
perfect. We strived to get recordings and playbacks to the highest quality
possible. It was easy once the mind set was created and procedures were
followed. Peoples jobs actually became easier and they were able to
concentrate on the creative end and not worry about the technical end.
Thus we got a reputation as a quality house. </div>
<div> </div>
<div>Hope this helps with the thought process.</div>
