"The recording medium disk, disk drive apparatus for recording data and reproducing data from a recording medium of disk, and,Reproduction method for reproducing data from a recording medium of disk. The first data representing user data and third data use the same codes for error correction.The first data structure has a first block of error correction and third data have a structure of a second block of error correction.This is the first data and the third data have their respective structures of block error correction appropriate for them.In particular,The density of the recording of the third party data is made less thick than the density of the recording of the first data and the number of codes of the correction of the first block of error correction is adjusted.A multiple of M, while the number of codes of the correction of the second block of error correction is set to N / m times the number of codes of the correction of the first block of error correction.So that a count of pieces of data of the second block of error correction is also N / m times a count of pieces of data from the first block of error correction.As a result, it is possible to provide a good recording technique of information of time of order in a disc of high density recording.
