ABSTRACT:
After OPC is executed on a DVD+RW, a value of an OPC counter assigned to a DCB of the DVD+RW is read and then temporarily saved in a memory, and then the temporarily saved value is incremented by +1. If an optical disc eject request is received, the value of the OPC counter assigned to the DCB is updated so as to be equal to the incremented value. If a write-operation-number display instruction is received, the value of the OPC counter assigned to the DCB is read and then displayed by display means as the number of write operations to the disc.
