Optical disk processing apparatus |
摘要 |
An optical pickup is opposed to an inner-radius portion of an optical disc that is set, and pits (a modulation signal) are read by applying laser light for a DVD to the inner-radius portion. The read-out modulation signal is decoded by inputting it to a CD decoder. If decoded disc information includes particular verification data, the optical disc is judged to be a legitimate optical disc of a particular type and formation of a visible image on the label surface is permitted.
