An optical disc and an optical disc apparatus having an improved error correction capability. In an optical disc on which is recorded data encoded using an encoding block of a pre-set data volume as a unit for encoding, a data volume V of the encoding block is the maximum number among data volume values of the encoding block that satisfies the relation V X (1+R) X D < L0, and that can be expressed by the powers of 2, where L0 is the innermost track length, R is the redundancy of encoding, and D is the code length per bit. In this manner, the encoding block is of a size corresponding or substantially corresponding to the entire innermost track of an optical disc. <IMAGE> |
