PROBLEM TO BE SOLVED: To more surely prevent data corruption caused by recording performance degradation at a low temperature, and also to prevent excessive limitation of a recording operation. SOLUTION: A testing write operation is performed to a storage medium only in accordance with a condition that temperature drops below a prescribed temperature. The permission/nonpermission of a recording operation is determined on the basis of the result. Since a recording operation is not permitted only when recording is actually impossible, the recording operation is not limited excessively. Since recording can be allowed only when recording is actually possible, data corruption is prevented more surely. COPYRIGHT: (C)2006,JPO&NCIPI
