    摘要： A data recording method comprising the steps of encoding user data into first error correcting codes having a first correction capability, encoding control information into second error correcting codes having a second correction capability higher than the first correction capability, generating a data stream containing the first error correcting code, the second error correcting code, and synchronization signals, wherein the second error correcting codes and the synchronization signals alternatively interleave the first error correcting codes, and recording the data stream.

    摘要： A disk drive has two channels of upper interfaces, and one channel is connected to a disk array controller, and the other channel is connected between a plurality of disk drives. A data disk drive reads the old data on the recording medium, calculates the exclusive OR of the old data and the corresponding data from the disk array controller, and transfers it to a parity disk as pseudoparity data from the other channel. The parity disk drive reads the old parity data on the recording medium, calculates the exclusive OR of the old parity data and the pseudo-parity data, and writes it as new parity data.
