ABSTRACT:
A system for erasing data stored on an optical storage medium includes a housing, a guiding means mounted within the housing for guiding the optical recording medium on which the data is stored, and a heating means mounted in spaced-apart opposition to the guiding means for heating the optical recording medium to, thereby, thermally erase optical data stored on the medium.
