摘要： A magnetic disk apparatus capable of generating a reference clock signal without using an external reference by writing a clock track only once using a head of the magnetic disk apparatus even if the head is of a read/write element separation type. Using the head of the magnetic disk apparatus, a clock track is recorded only once and the recorded clock track is played back to measure the total number of clock bits in one revolution. A time interval between servo sectors is determined by dividing the total number of clock bits thus measured by the number of servo sectors. By using as a timing reference the clock bits produced by playing back the clock track, the servo sectors are recorded in such a manner that they are located at the determined interval.

摘要： A servo write method capable of generating and recording correction data, to be used for compensating for repeatable position error caused by write errors of servo patterns, in a short time is presented. In the recording of the servo pattern, correction data for correcting revolution-synchronous components are generated from a position error signal which is obtained from the difference between a target position and a magnetic head position, and the correction data are recorded in servo areas on a disk.

摘要： Under existence of an impact and a vibration, a throughput and a reliability of a recording and reproducing operation in a magnetic disc apparatus are reduced. Accordingly, a mechanism for fixing a coarse moving actuator at an optional position is provided, at a time of following to a track, a motion of the coarse moving actuator is restricted and a positioning is performed by a fine moving actuator. Even when a vibration and an impact is applied from an external portion during the track following operation, it is possible to prevent the head position from being shifted and it is possible to perform a recording and reproducing operation. Further, it is possible to prevent adjacent data from being erroneously broken.

摘要： A voltage conversion apparatus includes a booster circuit, a boost stop circuit, a Zener diode, and a capacitor. The boost stop circuit includes a transistor. When an overvoltage equal to or larger than a breakdown voltage of the Zener diode is output to an output line of the booster circuit, the Zener diode is turned on. Accordingly, the transistor is turned on and a switching element is turned off to stop a boost operation. Further, the capacitor is charged through the Zener diode. Even when the Zener diode is turned off due to a drop in the output voltage after the stop of the boost operation, the transistor maintains its on state for a certain time by discharge of the capacitor. Thus, the stop of the boost operation is continued.
