1. A disk control apparatus that controls a disk driving unit that performs read/write of data with a head, the disk control apparatus comprising:
- a vibration detecting unit that detects a vibration of the disk driving unit using a rate of write fault occurrence, the rate of write fault occurrence being obtained from at least one of a shock sensor and the position signal; and
a disk control unit that controls the disk driving unit to switch a sensitivity of the shock sensor based on the detected vibration.

6. A computer-readable recording medium that stores a computer program for controlling a disk driving unit that performs read/write of data with a head, wherein
the computer program causes a computer to execute: -
detecting a vibration of the disk driving unit using a rate of write fault occurrence, the rate of write fault occurrence being obtained from at least one of a shock sensor and the position signal; and controlling the disk driving unit based on the detected vibration to switch a sensitivity of the shock sensor.

7. A disk control apparatus that controls a disk driving unit that performs read/write of data with a head, the disk control apparatus comprising:
-
a vibration detecting unit that detects a vibration of the disk driving unit; and a disk control unit that controls the disk driving unit based on the detected vibration, wherein the disk control unit rejects, when the vibration is detected, a seek error signal, and maintains a settling state. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
