VHS and cassettes can go diaf (lol mine already did! ;D). Other media typically aren't destroyed by the earth's own magnetic field by virtue of existing.

There are some interesting effects you can get with distorted tapes, but nothing you couldn't achieve digitally. As an archival medium, they are completely fail.

The advantage to them both was that they were the first home-recordable media that were widely available. A generation of djs, mixartists, and home recorders were born.
