OPTICAL DISK, OPTICAL DISK DEVICE, AND OPTICAL DISK PROCESSING METHODJP2006236523A

摘要

According to one embodiment an optical disk processing method according to this invention detects the reflected light from an optical disk having a first and a second recording layer in each of which first and second tracks are formed alternately from the inner edge toward the outer edge, determines a method of detecting the pits in the first and second recording layers on the basis of pit polarity information indicating the polarity of the pits included in the information reflected in the detected reflected light and of recording-layer identifying information to identify the first and second recording layers, and reproduces addresses from the pits in the first and second recording layers by the determined detecting method.
