Camcorder Instruction books recommend that you rewind mini dvd tapes periodically. Until now I have assumed that this simply means fast forwarding and then rewinding the tapes once a year, but I now wonder if I should only be forwarding each tape only to the end before storing for a year after which I rewind it to the beginning. This latter method would help prevent any "print through" from one layer of tape to the other such as used to happen with audio tapes. That may not be a problem for mini dvd tapes - but I don't know. Your comments would be appreciated.
