Abstract
An optical disk apparatus includes: a recording quality determination unit for, when a recording/reading unit has recorded data on an optical disk, reading the data recorded this time from the optical disk, and determining whether the recording quality of the data is at a proper level or not, wherein when the recording quality of the data has been determined to be not at a proper level, and the type of the optical disk on which the data has been recorded this time is a rewritable type, the recording/reading unit executes an erasing processing of erasing the recorded data on the recording area in which the data has been recorded this time in the optical disk, and executes a rerecording processing of recording the same data again on the recording area in which the data has been erased with this erasing processing.
Claims4
An optical disk apparatus comprising:
- a recording/reading unit for performing recording and reading of data with respect to an optical disk set in a main body;
- and
- a recording quality determination unit for, when the recording/reading unit has recorded data on the optical disk set in the main body, reading the data recorded this time from the optical disk, and determining whether the recording quality of the data recorded this time is at a proper level or not, wherein
- when the recording quality of the data recorded this time has been determined to be not at a proper level by the recording quality determination unit, and when the type of the optical disk on which the data has been recorded this time is a rewritable type, the recording/reading unit executes an erasing processing of erasing the recorded data on the recording area in which the data has been recorded this time in the optical disk, and executes a rerecording processing of recording the same data again on the recording area in which the data has been erased with this erasing processing, and, on the contrary, when the type of the optical disk on which the data has been recorded this time is not a rewritable type, executes a rerecording processing of recording the same data again on another recording area than the recording area in which the data has been recorded this time in the optical disk, and
- every time the recording/reading unit records a predetermined amount of data on the rewritable type optical disk, the recording quality determination unit determines whether the recording quality is at a proper level or not with respect to a predetermined amount of the data recorded immediately before.
