    Abstract: First error-processing data are generated (39) with respect to a predetermined amount 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 first error-processing data, and the second error-processing data. The data of record units are 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 the first error-processing data with respect to each of the record units. If errors cannot be corrected, at least errors are detected in the predetermined amount of data in each of the blocks with the second error-processing data. If errors are detected in N (N is a positive integer) successive blocks, all data in at least one block which is not positioned at an end of the N successive blocks are regarded as being erased, thereby correcting errors in the predetermined amount of data in the record units with the first error-processing data, thus producing reproduced data.

    Abstract: Method of recording on a record medium (4) by receiving a series of data elements, adding error detection and error correction data to each data element, moving some of the data in each data element to an adjacent data element to produce arranged data elements, and recording the arranged data elements in different sectors on a record medium (4). Upon reproduction of the arranged data elements from a record medium (4), some of the data in each arranged data element are moved to an adjacent data element to produce rearranged data elements. Errors in each rearranged data element are detected and corrected using data contained therein. A record medium (4) having concentric tracks on which a plurality of sectors are located stores data in each of the sectors. The data in each sector pertains to two different sectors so that the affect of a burst error on a particular sector is minimized.

    Abstract: Data recorded on such a recording medium as an optical disk, are reproduced excellently even when burst errors occur during reproduction, without reducing the data record capacity of the recording medium. A first error correcting code is generated for every block of a certain amount of data, and added to the corresponding block, a second error correcting code is generated for the every block and added to the other blocks than the block for which the second error correcting code is generated. These data and codes are recorded on the recording medium. When reproducing the data, recorded on the recording medium in blocks of data, whether or not detection correction is possible or not is judged based on the first error correcting codes included in the reproduced data. When the detection correction of a block is possible, the detection correction is performed, and when impossible, missing information is generated based on the second error correcting codes reproduced from the data blocks and corresponding to the block of which detection correction is impossible. Using the missing information and the first error correcting code, missing correction of the data block is performed.

    Abstract translation: 记录在这样的记录介质上的数据，即使在再现期间出现突发错误，也不会降低记录介质的数据记录容量，因而再现出色。 对于一定数量的数据的每个块生成第一纠错码，并将其添加到相应的块中，为每个块生成第二个纠错码，并将其添加到其它块，而不是第二个纠错码 代码生成。 这些数据和代码被记录在记录介质上。 基于包含在再现数据中的第一纠错码来判断在数据块中记录在记录介质上的数据是否可能进行检测校正。 当块的检测校正成为可能时，执行检测校正，并且如果不可能，则基于从数据块再现的第二纠错码并且与不能进行检测校正的块相对应地生成丢失信息。 使用缺失的信息和第一个纠错码，执行数据块的修正。
