|Not really stating a problem. There was a thread from 2010 that is now locked. I found it via a google search. There was a question I had searched on, and found, if it was possible to recover an earlier recording on a VCR tape that had been recorded over, and I have a response to that.|
The answer is maybe. If the 2nd recording is not perfectly aligned to the first, then you can see the background recording, but the quality will not be good, it will look like the tracking is way off, but the images are quite discernible as is the sound. I know this through a mistake in my VCR tonight where I went to play a tape recorded from a few nights ago and it wasn't there, instead, I got something else from weeks ago. I set it aside, looked at other tapes thinking I had the wrong tape. Then re-round the tape in question, played it again, and voila, it played corrected, no error, no tracking issues, and it showed a different speed. Somehow, it must have had a temporary glitch in the electronics or something that skewed the tracking, and it also went to a different speed...that part is key, I suspect. The two recordings need to be at different speeds. So all this to say if my recorder could play an old recording by error, then certainly there is sophisticated equipment out there that can recover old tracks, or maybe pieces of them.
