Record medium, and method for recording to and reproducing from a record medium

摘要

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. <MATH> <MATH> <MATH>
