摘要： This invention relates to a motor velocity control method and storage device for performing loading/unloading control of a head that reads from a storage medium in order to move it away from the storage medium. In order to detect accurate velocity from the counter electromotive voltage of the motor for performing loading/unloading control, the storage device comprises a storage medium 6, head 4, actuator 3, control circuit 19 and ramp 11. Velocity control is performed by using the velocity detected from the counter electromotive voltage of the actuator 3 in the unloading/loading control of moving the head 4 away from the storage medium 6. Moreover, the transient response voltage of the actuator is calculated and the detected voltage is corrected. Furthermore, the velocity offset coefficient for converting the counter electromotive voltage to velocity is calibrated. Also, the velocity correction coefficient for converting the counter electromotive voltage to velocity is calibrated. This makes it possible to obtain accurate velocity from the counter electromotive voltage.

摘要： A disk unit has a function of loading a head on a disk from a holding mechanism during a load operation and unloading the head from the disk during an unload operation. The disk unit includes a controller which controls a movement of the head so that the loading operation and the unloading operation are carried out in a specific region on the disk, and the specific region extends for an angular range smaller than 360°. Alternatively, the controller controls the movement of the head so that the loading operation and the unloading operation are carried out uniformly in a circumferential direction of the disk within a specific region on the disk.

摘要： This invention relates to a head loading/unloading method for moving a head that reads storage medium away from that storage medium, and makes optimal unloading operation possible. In a storage device comprising a storage medium 6, head 4, actuator 3 and control circuits 9, when the amount of continuous time when there is no access reaches the unload starting time, the head 4 is moved away from the storage medium 6. This unload starting time is made to be variable and is changed according to the state of the device. Therefore, an optimal unloading operation that corresponds to the state of the device is possible, that also has a balance among device life, access time and resistance to shock.

摘要： The magnetic disk drive system has a read head and a write head, writes data on the track of the disk, and reads data on the track of the disk. In the present invention, the distance between the heads in the circumferential direction of the disk is computed. The distance between the heads is computed based on the distance between the position of the write head where said data is written and the position of the read head where said data is read. The timing when data is written by the write head is determined by adding said distance to the position where the data is written. Thus, the efficiency of the format of the disk is improved.
