摘要

An object of the present invention is to provide an optical disc reproducing apparatus with high reproduction capability in the occurrence of various kinds of synchronization abnormality and defect sector reproduction of the optical disc reproducing apparatus.;Information read from the optical disc medium is stored using the frame synchronous counter value address conversion decoder 202, the lower ID address conversion decoder 203, the adder / subtracter 204, the upper ID address conversion decoder 205 and the adder 206 It is possible to store the data with high reproduction capability in the storage medium by converting it into an absolute storage address of the medium.
