Subject: More on the D/SVHS tapes
In reply to: axel 's message, "Re: D-VHS ON S-VHS TAPES" on 12:43:57 05/16/02 Thu

Ok, after more tests on the subject, I come up with two interesting results, one fairly understandable, one not really so...

A stated before, recording on S tapes is ok if you use very good tapes (Maxell BQ, Fuji H471 or even TDK XPpro).
Then, if on playback you get an error and the DSPC thingy, black screen, blue screen, ERR 200, ERR 201 or whatever, it is because the heads are dirty.
Probably an emulsion thing, maybe S tapes are fatter (as in reel to reel comparison between tapes, say Ampex 466 vs. 499) and leave too much on the heads.

So, solution 1:
Clean the heads using the 3M ASD HC SVHS cleaning tape ; it was made to clean the ADAT professionnal MTR recorders (all based on SVHS mechanism and using S tapes). It works wonders - you won't get the DSPC again for awhile and your S tapes will be read as D tapes. No glitches, no drop-outs, no DSPC, no nothing, fine and dandy.

solution 2:
unbelievable... forget about this S tape you recorded with a D signal, keep cool, don't panic and put it on storage.
Record one or two D tapes (D signal on a D tape) and then read your S tape - see?
It's as if D tapes were cleaning the heads too, enabling the machine the read the D signal of the S tape properly again...
I wouldn't know the technical whereabouts of this but it worked!

I still would rather use the 3M cleaning tape.
But, as life would have it, those are not available anymore since 3M closed its tape media division.

Since they're pretty cheap, go find a stock (each tape is valid for 20 cleanings) and use that every other month and everything should go fine.

hope this helps
