ABSTRACT:
A recording medium with a data format is provided. The data format includes frames and an ECC block. Each of the frames includes a plurality of n-level data, n being an integer satisfying n≧3, a clock mark that is n-level data for sampling the n-level data, and a frame sync that is n-level data for indicating a break point of the n-level data of a predetermined amount. The ECC block is a data block for error correction using a product code. The ECC block is formed by binary data of J×K words, where J is a natural number indicating the number of valid binary data in each frame, and K is a natural number indicating the number of frames when the n-level data are converted into binary data.
