摘要： According to one embodiment, a disk drive is disclosed to which a plurality of disk rotational speed modes can be set. The disk drive is configured such that input of servo data from servo sectors is thinned out by thinning out an output of an interrupt request to a CPU in a high-speed rotation mode. At the time, a disk controller obtains servo data reproduced from all the servo sectors at timing of servo gates and stores it to a register.

摘要： According to one embodiment, a disk drive is provided which corrects already existing offset information according to a variation of a disk runout amount caused by an occurrence of a disk shift. The disk drive effects a head position adjustment at a head positioning control time with the use of offset information stored in a memory. A CPU measures a variation in the disk runout amount and phase caused by an occurrence of a disk shift resulting from an external shock involved and updates the existing offset information with a correction offset information based on a result of measurement.

摘要： In a data-recording mode, a driver circuit supplies a recording head with a recording current corresponding to write data. In a degaussing mode, the driver circuit supplies the recording head with a degaussing current for eliminating the residual magnetism of the head as the recording current. The degaussing current has a rising period and falling period set longer than those of the recording current supplied in the data-recording mode.
