I recently recorded a very important student concert on DAT. As I was
transferring the tape to computer, I heard a high pitched noise from
the tape mechanism, before it grinded to a stop. I then realized my
Tascam DA-P1 chewed my tape.
I spent a long time trying to get the tape out of my Tascam DA-P1.
Luckily none of the tape broke; it was just wrinkled. So I proceeded to
put the tape back in to play it because I could not afford to loose
this audio.
It played, but I heard no sound whatsoever.
I then put in another DAT tape with previously recorded sound on it,
and again, no sound, no timecode/track numbers, even though the
mechanism was moving.
I figured my DAT machine was probably broken, so I tried another deck.
I first put in the non-chewed tape in and it played no problem. Then
the student concert DAT, and no sound. Put the first tape back in, and
no sound either! It seems like I had ruined or contaminated the heads
of two DAT machines!
Two days later, I tried the Tascam DA-P1 again and it worked no
problem. Did I temporarily ruin or contaminate the heads by feeding it
crumpled tape? Should I buy a head cleaner?

Viewed at this remove, I'd say: yes, and yes.
Tape transports are not in any way forgiving, and DAT's are still
mechanical devices. Do you have access to any local service that
you trust?
Good fortune,

If you run a crumpled tape over the heads you are pretty likely going to get
some tape oxide shedding and blocking up the heads - your assumptions are
correct. A tape head cleaner would certainly not do much harm if you follow
the instructions, but I have never found them to be particularly thorough.
To manually clean the heads requires some dismantling of the casing as far
as I recall and is a risky operation for the inexperienced anyway.
What you need to be aware of is the question of why the machine ate the tape
in the first place. If nothing has changed it may well do it again. The
only solution is a proper service, but this will not be cheap. There is an
outside chance that cleaning the heads properly will solve the problem, but
only if the eating of the tape was caused by a dirty/sticky head snatching
the tape. There are all sorts of other reasons for tape eating, and often
it is a combination of all of them that only a service can cure.
If you can't afford the service, you could perhaps take the machine to a
video repair place and see whether they would be prepared to just clean the
heads and transport manually for you - a DAT mechanism is just a minature
VCR really.

Unless you pressed the Record button (or the electronics did it for
you) it's pretty hard to erase a DAT, so chances are the tape is OK
other than perhaps for a dropout where it's been creased. But it may
be that in your struggle to retrieve the jammed tape and put it back
into the shell, it got twisted and you're trying to play it thorugh
the back side. Give it a thorough autopsy.

I sure hope it wasn't one of those "extra-long" DAT tapes, using the
very-thin tape. Always to be avoided, in ANY tape format.
This recent tape chewing event has caused me to think about getting
tapeless solutions; such as digital recorders. Can anyone recommend a
portable digital recorder with the same quality and inputs/outputs as
the Tascam DA-P1?
I'd need:
S/PDIF in/out, RCA/phono in/out, 2 XLR mic in with phantom power,
44.1/48 khz recording, built-in limiter, timecode would be nice, and
some kind of removable memory card would also be nice.

I've notived a decline in the quality of DAT tapes lately. We used HHB tapes
for years, but the last batch had a higher percentage of defective tapes. I'm
going to try some data tapes, but DAT is over for all intents and purposes. I
am keeping a machine or two for playing back old tapes but I don't recommend
DATs anymore except for our DA-P1 that still works OK for field work.
There are two schools of thought about the FF/REW thing. I gave up on it and it
hasn't seemed to make any difference for DAT and DTRS tapes.

90's are still on the edge... and depending on where you got the tape, as
to how long it may have been sitting on the shelf or in otherwise unknown
conditions. Exercizing the tape has always been second nature for me,
so I can't say whether or not it always has any affect, because I've never
failed to do it.
A DAT head cleaner isn't all as bad as some people seem to think when
it comes to claiming excessive wear on the head... it will still make a nice
pass at cleaning the transport parts that come in contact with the tape.
I've used them religiously and since I've *never* lost a DAT head I can't
make any claims about excessive wear.
I recommend keeping a tape machine in the path as a backup until you
gain confidence in other storage mediums.
I think Mike Rivers has the best possible explanation at this point, for that
specific tape failing to read.... sounds very plausible to me (been there....)

If there was such, I'd have one. Try the Fostex FR2 or the Edirol R4,
or for some more money, the Sound Devices 722(?).

If you're willing to settle for only a removable memory card (no disk)
the Marantz 660 looks like it might work for you.

You _sure_ it wasn't a 90 meter tape?
