    Default Quick Tape Erasure

    Can anyone help with a way to quick erasure of DV tapes, in the days of reel to reel audio tapes we had a bulk tape eraser that you could pass over a spool of tape and it would erase the whole tape, it had a big mains coil inside, I tried it on a DV tape yesterday and it made no difference at all.

    Is there any other way of achieving this.

    Modern metal tape - much higher coercivity, hence very hard to erase, maybe those sooo cool neodynium magnets will do it?

    I also 'think' i saw a dv eraser on e bay ages ago... maybe...

    Thank you for your reply Mark.

    Is there such a thing as a DV eraser, I've never seen one or even heard of one, would be interested of any information. ........perhaps I'll have a "Google" around.

    Cheers for now

    Personally I'm curious as to why you feel the need to erase a tape at all.

    You can just record over them of course if you wish to reuse them. I never use a minDV tape more than once. They prove to be my best backup of my original work and I often find littel hidden gems on them that are useful later as well.

    I had a Google about when this post was first put up.

    I came across the issue about high coercivity as well. It seems that DV tapes require a degausser with a fair amount of oomph to wipe the data. The prices I came across for suitable machines were silly, starting off in the region of $1800, and rising to $3500.

    I thought for that amount of money, you could buy a LOT of new tapes....

    Presumably the tapes are designed this way to avoid everyone's holiday tapes getting wiped everytime they go through security at customs.

    Actually it all started as a bit of an experiment as I had the degausser, I came across it whilst sorting out some old reel to reel audio tapes, and thought I would just try it out on a DV tape (it's amazing what you get up to when things are quiet) and just thought if it worked and i wanted to erase a tape it would save me putting it through the camera, I don't bother usually.
