PROBLEM TO BE SOLVED: To provide a storage medium control device for preventing decrease in the reliability of data saving with a non-redundant structure. SOLUTION: A storage medium control device is provided for communicating with a higher-order device, for managing/controlling an information storage device body configured with physical storage media to store information with a non-redundant structure. The device includes: a region allotment processing means 35b for allotting each physical recording medium to a user useable region AR1 and to a substitute sector region AR2; a fault sector detecting means 35c for checking sectors of the user useable region allotted by the region allotment processing means in initialization processing of the non-redundant structure to detect a fault sector from which information is not read out; and a fault sector exchange processing means 35d for exchanging the detected fault sector of the user useable region AR1 with a normal sector of the substitute sector region AR2.
