摘要： Embodiments of the invention reduce a possibility that a head will collide with a medium when the clearance between the head and the medium is adjusted by using a medium, and sufficiently reduce the clearance even at an initial stage of accessing a data area. In one embodiment, a hard disk drive (HDD) keeps a heater in an OFF state for a period of time from the start of seek operation until the specified timing after a following mode starts. This prevents a head element from colliding with a magnetic disk, and also prevents flying properties from changing due to the deformation of the ABS. In the above specified timing, the heater is switched from OFF to ON. Specifically, for example, on completion of seek operation, in the timing in which a head arrives at a target track, or in the timing in which an HDC/MPU enters the following mode, the heater is turned ON.

摘要： Embodiments of the invention allow a heater to reduce the clearance between a head element section and the magnetic section while reducing the risk of collision between the head element section and the magnetic disk during load/unload. In one embodiment, an HDD judges whether a heater is ON or OFF after the load process is started. If the heater is found set to ON, the HDD sets the heater to OFF. With the heater kept OFF, the HDD starts the actuator pivoting. If the heater is found set to OFF, the HDD moves the actuator from the parking position to the magnetic disk with the heater kept OFF. Upon completion of the load process, the HDD goes to the subsequent process. Since the heater is OFF during load, the risk of collision between the head element section and the magnetic disk is reduced.

摘要： Embodiments of the present invention help to achieve a read error recovery, and suppress decreases in the capacity of the disk drive device and degradation in performance. In one embodiment, a hard disk drive (HDD) performs following control without use of repeatable run-out (RRO) compensation information on a magnetic disk in a normal reading process. When an error occurs in a normal reading process, the HDD moves a read element to a position different from a target position of the normal reading process. At the position where the read element has been moved, the read element reads out the RRO compensation information. In a recovery procedure for the reading process where the error has occurred, the HDD performs following control with compensation by the servo compensation information read out by the read element.

摘要： Embodiments of the present invention provide accurate pitch control of a servo write track. A Self-Servo-Write (SSW) according to an embodiment of the present invention determines a reference APC by reading a mark formed on the recording surface corresponding to the propagation head prior to starting the product servo pattern writing. The accurate size of the mark in the radial direction is known previously. The reference APC is for determining the track pitch, and by using the mark with the determined size, the product servo patterns can be written with a desired and accurate track pitch.
