APPARATUS AND METHOD FOR PERMANENTLY DELETING DATA OF OPTICAL DISK

摘要

The present invention relates to a method for eternally erasing data recorded on an optical disk by generating an optical scratch on the optical disk. More particularly, the present invention relates to a method for eternally erasing data recorded on an optical disk by disturbing a laser beam at a predetermined frequency and amplitude while irradiating the laser beam having a predetermined power and at the same time moving a sled.
