Abstract:
A method of controlling access to a disk medium when a condensation sensor provided in a disk drive detects condensation, information recorded on the disk medium being read by a head in the disk drive, the method comprising:determining, from a detection result of the condensation sensor, whether condensation occurs in the disk drive; waiting for a predetermined period of time if it is determined that condensation occurs in the disk drive, wherein the waiting occurs when the head is retracted to a predetermined position, wherein the waiting includes rotating the disk medium at a higher speed than a standard speed for the predetermined period of time; executing a test reading operation on the disk medium after the predetermined period of time; and executing normal access to the disk medium if the test reading operation succeeds, when a host using the disk drive issues a request for the normal access to the disk medium.
