Abstract:
In an optical disc apparatus that records and reproduces data onto and from an optical disc in units of predetermined block, an information divider divides the data so as to reduce an amount of the data included in each of blocks when a recording state of the optical disc does not satisfy a predetermined criterion, and reproduces recording data in units of the block by adding sub-information including a value indicating the amount of the data included in each of the blocks. An error-correction encoder circuit encodes the recording data in a first error-correction code format, and a recorder converts encoded recording data into a recording signal, and records the recording signal onto the optical disc. A quality evaluator circuit produces an evaluation value indicating a recording quality based on a result of reproducing the recording signal recorded on the optical disc.

Claim (Index 2):
The optical disc apparatus according to  claim 1 ,\n wherein the sub-information includes control data that includes a value indicating the amount of the data included in each of the blocks; and an error-correction parity code for the control data used when error-correcting the control data with a second error-correction code format, and wherein a redundancy degree of the second error-correction code format is higher than a redundancy degree of the first error-correction code format.
