METHOD FOR RECORDING/REPRODUCING DATA, DATA REPRODUCING DEVICE, AND RECORDING MEDIUM

摘要

Data recorded on such a recording medium as an optical disk, are reproduced excellently even when burst errors occur during reproduction, without reducing the data record capacity of the recording medium. A first error correcting code is generated for every block of a certain amount of data, and added to the corresponding block, a second error correcting code is generated for the every block and added to the other blocks than the block for which the second error correcting code is generated. These data and codes are recorded on the recording medium. When reproducing the data, recorded on the recording medium in blocks of data, whether or not detection correction is possible or not is judged based on the first error correcting codes included in the reproduced data. When the detection correction of a block is possible, the detection correction is performed, and when impossible, missing information is generated based on the second error correcting codes reproduced from the data blocks and corresponding to the block of which detection correction is impossible. Using the missing information and the first error correcting code, missing correction of the data block is performed.
