Re: [ARSCLIST] F1 difficulties
Jeff,
While I can't speak for 1/2" VHS or Beta tapes, we have run across SSS
problems with 3/4" U-Matic tapes recorded using the Sony F1 system. It's
a real pain...
The best solution we have found is to swap out the shell and guides, and
try a commercial videotape cleaning device. There are units made by both
RTI and Media Matters, (Jim Lindner's new company), as well as some
older equipment made by Recortec. I am very impressed with the unit that
Jim has designed for 3/4" U-Matic tapes, but it's not cheap! RTI also
makes model for 1/2" videotape, but we have not tried these for SSS. In
any event, the tapes will usually require multiple passes.
Transferring these tapes is another matter entirely. We have done a
number of modifications on both the decks and the PCM 701 processors we
own to allow us to manipulate the servo operation of the video recorder
and adjustment of the lock parameters on the 701 bitstream. I'm sure
we'll never recoup the man hours that have been invested in this effort...
There are far too many issues than can be addressed here, but I would
recommend you try and obtain a professional machine, lock it to a house
sync generator, and make sure that the line error correction is
disabled! Make sure to set the playback for B & W (although some decks
will do it by default).
Best of luck!

here? Any help would be much appreciated.
Hi, Jeff,
There have been lots of reports about SSS from videotape in 3/4"
sizes. I wouldn't be surprised if you had it. After all, it's Ampex!
(sigh).
On the AMIA list, Jim Lindner has cautioned us against baking
anything, but especially videotapes. He has good reasons for it,
including the possibility of the tape deforming and/or snapping back
to an earlier geometry prior to tensilization. I hope I'm quoting him
well in this brief summary.
Jim got his start restoring 1/2" EIAJ videotapes, including Andy
Warhol's as I understand it. I have a lot of respect for him. Jim
Wheeler, a videotape engineer from Ampex is also on the AMIA List.
I think joining and asking your question on AMIA-L would be a good
source of information.
I do F1 transfers, but I haven't run across a sticky F1 tape yet (for
which I'm thankful).
The other source of information is Specs Brothers in New Jersey. They
are experts in cleaning tapes. Peter Brothers is also on AMIA-L.

This is an interesting crossover issue from an obviously crossover
technology.
Cheers,
