摘要：First error-processing data are generated (39) with respect to a predeterminedamount of data, and second error-processing data are generated (40) with respect to
each of a plurality of blocks produced by dividing the predetermined amount of data.Data of record units are generated from the predetermined amount of data, the firsterror-processing data, and the second error-processing data. The data of record unitsare recorded (8) on and reproduced from a recording medium (4). Errors are corrected(2) in the predetermined amount of data in the reproduced data of record units with thefirst error-processing data with respect to each of the record units. If errors cannot becorrected, at least errors are detected in the predetermined amount of data in each ofthe blocks with the second error-processing data. If errors are detected in N (N is apositive integer) successive blocks, all data in at least one block which is not positioned atan end of the N successive blocks are regarded as being erased, thereby correctingerrors in the predetermined amount of data in the record units with the first error-processing data, thus producing reproduced data.
