Abstract:
By avoiding the problem that in a hybrid optical disc, an optical pickup suitable for a standard-density recording area cannot operate as desired in a high-density recording area, damage to the disc drive or optical disc is prevented and optimal control is enabled. Access operation identification information such as reproducing identification information indicating whether or not information recorded in the user data area of the optical disc can be reproduced under the reproducing conditions of the optical disc driving apparatus is recorded in the lead-in area. 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, because reproducing or recording compatibility with the optical disc is lacking.
