Abstract
There is disclosed a method for optically recording data in data areas of a disk-like recording medium in which servo signal areas are formed along the track in alternation with data areas. Parity codes for error correction are generated and affixed in at least one direction, that is, in the column or row direction, of a two-dimensionally arrayed data block, and the two-dimensionally arrayed data affixed with the parity codes are supplied sequentially to an optical pickup along any one of the column and row directions so as to be recorded in respective ones of said data areas. The number of the data in the direction of reading of the two-dimensionally arrayed data is selected to be an integer times the data number that can be recorded in each data area provided on said disk-like recording medium, when the former is intended to be greater than or equal to the latter, or the data number that can be recorded in each such data area is selected to be an integer times the number of the data in the direction of reading of the two-dimensionally arrayed data when the inverse relation is intended.
