A storage device receives and holds a storage medium that is subjected to first servo writing processing for writing servo information, a Gray code of which is offset, from an inner cylinder or an outer cylinder to a predetermined cylinder and, after the first servo writing processing, subjected to second servo writing processing for writing servo information from an opposite direction to the predetermined cylinder and in which Gray codes are written to be offset not to overlap in the first or second servo writing processing and the pieces of servo information having different mark patterns are written in the first servo writing processing and the second servo writing processing. The storage device acquires cylinder information and mark patterns from the servo information written in the held storage medium and controls a position of a head based on the acquired cylinder information and mark patterns.

Offtrack amounts corresponding to every servo in which data writing has been completed is stored in a storage unit. Offtrack amount corresponding to a next servo frame, which is a servo frame present next to a servo frame for which data has been written, is calculated from the offtrack amounts stored in the storage unit. Based on the offtrack amount of the next servo frame, it is decided whether data needs to be rewritten in a sector present before the next servo frame.

Upon obtaining a detection signal of a shock sensor that detects a shock applied to an apparatus for output, a write disabling unit disables writing by a head on a medium over a predetermined time corresponding to a shock convergence. A determining unit determines, during the write disable, whether an output of the shock sensor is a detection output of the shock sensor due to a shock or an erroneous detection output of the shock sensor due to power supply fluctuations. A sensitivity control unit increases a detection sensitivity of the shock sensor when the determining unit determines that the output is a detection output due to the shock, and decreases the detection sensitivity of the shock sensor and clears the write disable when the determining unit determines that the output is an erroneous detection output due to power supply fluctuations.

A disk device includes a plurality of recording surfaces each of which having a recording area for recording data. An area or a width in a radial direction of an effective area set to be capable of recording the data in the recording area on at least one of the recording surfaces is different from that in the recording area on other of the recording surfaces.

A head position control device controls the position of a head with respect to a disk where post code is assigned to a servo frame. Servo frames of a disk is constituted by a servo frame not having a post code recorded in an inner side zone and a servo frame having a post code recorded in an outer side zone. The device reads the servo frame, demodulates a current position from the servo frame, drives an actuator according to the modulated position, and controls the position of the head to a target position. While implementing a high TPI, the inspection time for post codes can be decreased with a servo frame occupying ratio in consideration of the data format.

It is an object of the present invention to provide a control unit for an electric power steering apparatus for accurately detecting an abnormality of a steering angle sensor without forming the steering angle sensor as a double system or using an expensive position detection sensor. The object is achieved by calculating a relative steering angle by using inexpensive position detection sensors disposed at a motor of the electric power steering apparatus to output binary values and comparing a change amount of an absolute steering angle detected by the steering angle sensor and a change amount of the calculated relative steering angle with each other to thereby detect the abnormality of the steering angle sensor.
