I strong magnet can be used to wipe the information.
Also some document shredding companies have equipment that can shred the tapes.

Subject: [DCHAS-L] Still Another Question
Thank you for all your helpful responses to my question about hazardous high school chemicals. One more question has arisen: How could an organization dispose
of 300-400 videocassette tapes with sensitive information? I was asked about chemical treatment – or burning, and would appreciate your advice.
