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

摘要

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 (110) includes a recording controller (121) 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 (125) 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.

主权项

1. An information processing device for recording data in a disk array including a plurality of portable information storage media, the information processing device comprising:
a plurality of drive devices which respectively record the data in the plurality of the information storage media; and a control section which controls the plurality of the drive devices for recording the data in the disk array by striping the data, each of the plurality of the information storage media including:
a user area having a plurality of data blocks for recording the data, anda management information area in which recording failure area information is recorded, the recording failure area information including: information indicating which information storage medium, among the plurality of the information storage media of the disk array, has a recording failure area in which the data is missing; and information indicating a position of the recording failure area in the information storage medium that has the recording failure area, the control section including:
a data recording section which records the data in the plurality of the data blocks of the plurality of the information storage media by striping the data, and records, in at least one parity block, at least one parity data for use in recovering data in the data block, among the plurality of data blocks, in which the data is missing, andan area information recording section which records, in a case where recording has failed in at least one of the drive devices at a time of recording the data, the recording failure area information in the management information area of at least one of the information storage media, wherein the management information area further includes array management information for managing a recording state relating to the disk array, the array management information includes:
array type information for identifying a recording system of the disk array,array component number information indicating how many of the information storage media are included in the disk array,array number information indicating an ordinal number of the respective information storage media in the disk array, andan array configuration information table relating to all the information storage media of the disk array, in which the array number of the respective information storage media included in the disk array, and a medium identification number for uniquely identifying the respective information storage media are correlated with each other, and the area information recording section records the array management information in the management information area at a timing when an initialization processing for configuring the disk array is performed.
