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.
Claims5
An optical disc recording/reproducing apparatus that records and reproduces information on and from an optical disc, the optical disc recording/reproducing apparatus comprising:
- a system controller that
- after executing optimized power control (OPC) for setting output laser light of an optical pickup to optimum power, updates a value of an OPC counter assigned to a predetermined area of the optical disc by incrementing the value of the OPC counter by 1, and
- if a write-operation-number display instruction is received when information is being read from the optical disc, causes a display means to display the updated OPC counter value as a number of times writing has been performed to the optical disc.
