ABSTRACT:
A method of overwriting data in a linking loss area. The method includes the operations of (a) determining whether or not the first sector of a block in which it is desired for data to be recorded is a linking loss area, and if it is determined that the first sector is a linking loss area, reading the previous block; (b) modifying data type identification information of the last sector of the previous block after completing reading the previous block; and (c) recording data in blocks starting from the previous block. According to this method, based on determination of whether or not the first sector of the block in which it is desirable to record data is a linking loss area, data is recorded in the blocks starting from the current block or from the previous block so as to prevent errors in reproducing. By doing so, the method improves error correction effects.
