Storage medium control device, storage medium managing system, storage medium control method, and storage medium control program

A storage medium managing system, comprising:

• an information storage medium device main body which is configured with a plurality of physical storage media to be capable of storing information with a non-redundant structure;
• a storage medium control device for managing/controlling the information storage device main body;
• and
• a higher-order device that is communicable with the storage medium control device, wherein
• the storage medium control device includes:
• a region allotment processing device which performs processing for allotting each of the physical recording media to a user useable region and to a substitute sector region, respectively;
• a fault sector detecting device which performs processing for checking sectors of the user useable region allotted by the region allotment processing device in initialization processing of the non-redundant structure to detect presence of a fault sector from which information cannot be read out;
• and
• a fault sector exchange processing device which performs processing for exchanging the fault sector of the user useable region detected by the fault sector detecting device in the initialization processing with a normal sector of the substitute sector region of the physical storage media.

A storage medium control method for managing/controlling an information storage device main body which is communicable with a higher-order device and is configured with a plurality of physical storage media to be capable of storing information with a non-redundant structure, the method comprising:

• allotting each of the physical storage media to a user useable region and to a substitute sector region, respectively;
• detecting presence of a fault sector from which data cannot be read out by checking the sectors of the user useable region that is allotted, at a time of initialization of the non-redundant structure;
• and
• exchanging the fault sector of the user useable region that is detected by checking the sectors of the user useable region, at the time of initialization with a normal sector of the substitute sector region of the physical storage media.

A computer readable recording medium for storing a storage medium control program for allowing a computer, which is provided to a storage medium control device capable of communicating with a higher-order device and capable of managing/controlling an information storage device main body that is configured with a plurality of physical storage media to be able to store information with a non-redundant structure, to execute:

• a region allotment processing function which performs processing for allotting each of the physical recording media to a user useable region and to a substitute sector region, respectively;
• a fault sector detecting function which performs processing for checking sectors of the user useable region allotted by the region allotment processing function in initialization processing of the non-redundant structure to detect presence of a fault sector from which information cannot be read out;
• and
• a fault sector exchange processing function which performs processing for exchanging the fault sector of the user useable region detected by the fault sector detecting function in the initialization processing with a normal sector of the substitute sector region of the physical storage media.
