Hi Sonia,
If you have a stack of tapes it might be worth the ten minutes seeing if Tech Rentals or an office equipment supplier to military contractors similar has a tape degausser in their rental stock. These are big electromagnets, usually intended to erase low-level classified e-waste. For example: <http://www.veritysystems.com/degaussers/degausser.asp?id=1240> They'll easily wipe a big box of tapes in a day's rental. They're designed to wipe traditional 1/2" reel tapes, so they'll certainly work for MiniDV.
