Abstract:
An optical disc recording device includes: an optical disc device to record optical recording data onto an optical disc; a recording data assigning unit to divide a recording region on the optical disc into multiple divisions, part as a data region, assign optical recording data thereto; a redundancy data calculating unit to calculate redundancy data for restoring recorded data; a redundancy data assigning unit to take divided regions other than the data region as a redundancy region, and assign the corresponding redundancy data thereto; a recording/playing device having a recording capacity greater than the data region; and a recording control unit configured to record optical recording data in the data region and also at least a part thereof in the recording/playing device, cause the recording/playing device to play the optical recording data recorded therein at the time of calculating redundancy data, and record calculated redundancy data in the redundancy region.
