ABSTRACT:
To provide an optical disk drive having an enhanced replaying capability in case of an abnormality occurring in various kinds of synchronization of the optical disk drive or in replay of a defective sector. A frame synchronization counter value address translation decoder, low order ID address translation decoder, adder/subtracter, high order ID address translation decoder, and adder are used to translate information read from an optical disk medium into an absolute storage address in a storage medium, and thus data that is highly replayed can be stored in the storage medium.
