Thanks Doug, Jim and Rudy for responding--I'll let you know if the
data recovery trick works--

>I have been using a Sony MZ-R90 for field recording for a couple
years now...the message "DISC ERR" appeared in the
recorder window. Consulting the owner's manual, I find that this
message means "disc damaged or does not contain proper recording or
editing data"....Is the data on the disc somehow accessible? I'll
also post my query to the MD list.
You probably got this answer on the MD list, but just in case: Sounds
like a damaged table of contents. DO NOT RECORD anything else on that
disc, your previous audio is probably still there. The problem is,
the player can't find its way to the audio.
On some recorders, such as the SHarp 702, you can "trick" the MD into
letting you remove a disc without it knowing. then, you put the
"damaged" disc in and perform some simple TOC edit, like renaming a
track. Then "eject" the damaged normally, and the first disc's TOC
will be written onto the second disc, which is currently in the
recorder. This clobbers the corrupt TOC, replacing it with the TOC of
the first disc.
Of course, if this works, your track IDs will have nothing to do with
where your recordings actually started and stopped, but you can play
the whole disc off to another recorder and your audio is saved. I've
done this once, and it worked for me.
