Information processing device, information processing method, and information storage medium

An information processing method for recording data in a disk array constituted of a plurality of portable information storage media, each of the plurality of the information storage media including a user area having a plurality of data blocks for recording the data on the basis of the data block, and a management information area in which recording failure area information is recorded, the recording failure area information indicating information relating to a recording failure area in which the data is missing,

• the recording failure area information including information indicating the information storage medium having the recording failure area, and indicating a position of the recording failure area in the information storage medium, out of the plurality of the information storage media constituting the disk array, the method comprising:
• a data recording step of controlling a plurality of drive devices to record the data in each of the plurality of the information storage media in such a manner as to record the data in the plurality of the data blocks of the plurality of the information storage media by striping the data, and in such a manner as to record, in at least one parity block, at least one parity data for use in recovering data in the data block in which the data is missing, out of the plurality of the data blocks, and
• a recording failure area information recording step of recording, 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.

A portable information storage medium for recording data, comprising:

• a user area including a plurality of data blocks for recording the data on the basis of the data block;
• and
• a management information area in which recording failure area information is recorded, the recording failure area information indicating information relating to a recording failure area in which the data is missing, wherein
• a plurality of the portable information storage media constitute a disk array,
• the data obtained by striping and being stored in the plurality of the information storage media, and parity data for use in recovering data in the data block in which the data is missing, out of the plurality of the data blocks, are recorded in the user area, and
• the recording failure area information includes information indicating the information storage medium having the recording failure area, and indicating a position of the recording failure area in the information storage medium, out of the plurality of the information storage media constituting the disk array.
