Information processing device, information processing method, and information storage medium, including storage of information indicating which medium among plural media has a recording failure area and a position in the medium of the recording failure area

Abstract

Recording failure area information includes information indicating an optical disk having a recording failure area in which data is missing, and indicating a position of the recording failure area in the optical disk, out of the optical disks constituting a disk array. A controller () includes a recording controller () which records data in data blocks of the optical disks by striping the data, and records, in at least one parity block, at least one parity data for use in recovering data in a data block in which the data is missing, out of the data blocks; and a management information updater () which records recording failure area information in a management information area of at least one of the optical disks, in the case where data is missing in at least one of optical disk drives at the time of data recording.
