Data Rot

I thought this was interesting.

If she ever wants to see her movie again, constantly pulling it out of its storage case and playing with the magnetic tape is a sure way to make sure no one ever sees it again. The way she's messing with it makes the data archivist in me cringe. Even the slightest rubbing of the tape creates a microscopic magnetic field, destroying whatever data was on that section.

It is possible to forensically retrieve that data, but her constant handling makes it less and less probable. There's a reason why cassette tapes, video tape, floppy disks, and reel to reel recordings went out of vogue -- the media is inherently unstable.
