COPY PROTECTED OPTICAL DISC MANUFACTURING METHOD AND COPY PROTECTED OPTICAL DISC

摘要

A copy protected optical disc manufacturing method and a copy protected optical disc are provided. The method includes the step of inserting at least one predetermined optical head ditching (OHD) area, in which tracking of a light beam cannot be performed normally during a reproducing operation of an optical disc reproducing apparatus, between areas corresponding to contents. The copy protected optical disc cannot be copied using a recordable optical disc apparatus. Even if the copy protected optical disc is copied by an unknown method, a copy disc cannot be normally driven by an optical disc reproducing apparatus.
