摘要： PROBLEM TO BE SOLVED: To highly accurately move a magnetic head to a target position at a high speed corresponding to characteristics unique to the VCM or the like of each disk device.
SOLUTION: An FF current plus gain adjusting part 130 adjusts acceleration current data or saturated acceleration current data based on the determination result of a position determining part 120 at the time of finishing seeking, and an FF current minus gain adjusting part 150 adjusts deceleration current data based on the determination result of a speed determining part 140 at the time of finishing seeking. Based on an error between an FF position track and a real position track, an FF position track adjusting part 100 corrects FF position track data stored in an FF position track generation part 50, and adjusts a last reached position to match a target position.

摘要： PROBLEM TO BE SOLVED: To provide a mapping method of a disk drive in which track search time is improved. SOLUTION: In the mapping method, a plurality of logic track numbers is mapped onto a plurality of physical tracks of a disk drive. The method includes (1) a step in which a gray code offset of a recording and reproducing head that makes an access to a disk surface is determined for each disk surface within the disk drive and (2) a step in which logic track numbers are continuously assigned from the physical tracks corresponding to the gray code offset of the recording and reproducing head for the physical tracks of the surface of each disk and physical tracks, where the logic track numbers are assigned, are generated. Thus, the distance between the actual locations of the logic track and the assigned physical track becomes shorter, the track search distance is reduced and the track search time is improved.

摘要： PROBLEM TO BE SOLVED: To provide a storage device and a movement control method for an actuator, having outstanding shock resistance and vibration-resistance capability, and permitting fast ramp load/unload operation.
SOLUTION: A position of a magnetic head is obtained by a position detector 48 with a BEMF value in proportion to the moving velocity of the actuator obtained, from a VCM counter electromotive force detection circuit. A position judging unit 49 judges whether the magnetic head matches a position threshold Th 1 corresponding to the position where it collides the ramp. When matched, by a band switching device 47, a process for increasing the controlled variable such as switching to a broadband side, a band for PI control by a PI controller 46 for a feedback control system for the actuator is performed. By the position judging unit 49, the position judging is also performed for the position where change in the velocity starts or the position where change in the velocity starts reducing, and by the band switching device 47, switching the band for the PI control, and the like, is performed.

摘要： PROBLEM TO BE SOLVED: To shorten a time necessary before the start of file reproduction.
SOLUTION: The data reproducing device interrupts disk analysis when the designated number of files is detected during the disk analysis, and starts the reproduction of the detected files. Then, the device continues the disk analysis by using a free time for which it is not neccessary to access a disk during the file reproduction, and completes the disk analysis of one disk as a whole.

摘要： PROBLEM TO BE SOLVED: To prevent reduction in operation performance caused by positional shifting when switching the heads regarding the correction method of a disk device having positional shifting in the servo signals in circumferential and radial directions between a plurality of disks. SOLUTION: As the countermeasures for circumferential shifting, the sector number on a disk 10 is changed on a table 54 for each head. Circumferential direction positions are made to match between individual devices to remove the individual differences of the devices, thereby improving the performance. Since servo gate time is corrected on a table 62 matching the eccentricity of the disk 10, a signal is accurately detected to improve the detection accuracy of servo signals. Further, as the countermeasures for radial direction shifting, the track number on the disk 10 is changed on a table 46 based on a shifting value in which a reference head is a reference, the individual devices are equally positioned radially.
