Optical Disc, Optical Disc Driving Apparatus, Optical Disc Driving Method, Data Processing Apparatus, and Optical Disc Recording/Reproducing Apparatus
摘要:
By avoiding the problem that in a hybrid optical disc with a standard-density recording area and a high-density recording area, an optical pickup designed to be suitable for the standard-density recording area cannot operate as desired in the high-density recording area and may cause a malfunction, damage to the disc drive or optical disc is prevented and optimal control is enabled. Access operation identification information such as reproducing identification information 225 indicating whether or not information recorded in the user data area 222 of the optical disc can be reproduced under the reproducing conditions of the optical disc driving apparatus is recorded in the lead-in area 222. The optical disc driving apparatus reads this type of access operation identification information, compares it with access operation identification information possessed by the optical disc driving apparatus, and if they do not correspond, does not carry out access operations by the optical head to the user data area 222, because reproducing or recording compatibility with the optical disc 201 is lacking.
