ABSTRACT:
Deteriorated or aged magnetic recording media exhibiting undesirable properties such as shed, stickiness or squeal are restored to playable condition having no such objectionable properties by heating the media to an elevated temperature and for lengths of time sufficient to restore the media. A typical temperature used is 54.degree. C. and a typical effective time is 16 hours. Ambient humidity is suitable. The restored media can be used to transfer data or information to new media. Restored media can also be again heat treated for restoration purposes, if it deteriorates again.
