Abstract: 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.

Abstract: The present invention aims to provide an item-carrying system in which a robot can perform an item-receiving motion without giving the human a sense of discomfort when receiving it from the human.

Abstract: In a legged mobile robot control system having leg actuators each driving the individual legs and arm actuators each driving the individual arms, an external force acting on the right arm is detected, operation of the right arm actuators is controlled to produces a handshake posture, and operation of the leg actuators is controlled based on the detected external force acting on the right hand during handshaking, thereby improving communication capability by enabling it to shake hands with humans and to maintain a stable posture during the handshaking.

Abstract: 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.

Abstract: A magnetic disk apparatus includes an actuator for moving a head to a position above the magnetic disk in a servo track movement operation, a range limiter for limiting a movable range of the actuator, a range specifier for setting a specific range of the actuator in the movable range of the actuator, and a control unit. The control unit enables writing a servo signal into the specific range at servo track movement pitch based on servo tracks recorded with the servo signal, correcting the servo track movement pitch on the basis of the number of servo tracks in the specific range and executing control to write the servo signal at corrected servo track movement pitch.

Abstract: It is an object of the present invention to provide a magnetic disk apparatus capable of recording a servo signal onto the surface of a magnetic disk with a high degree of reliability and a high degree of efficiency without using an external write apparatus and capable of recording a predetermined servo signal onto the surface of a magnetic disk even if dimensional variations of a recording/reproducing device of a head exist.

Abstract: In a magnetic disk device after being sealed, just when a magnetic head is loaded onto a disk on which any signal is not recorded yet, a write current to the head that the magnetic disk device itself has is turned on and off to thereby write a recording region detecting signal at the loading point on the disk. In addition, a product-purpose recording region is provided between this signal-recorded position and the inner periphery (or outermost periphery) to which the head is regulated by a stopper. According to the present invention, the recording region can be specified by the disk device itself, and self servo-write can be performed to write a designed number of tracks at a precise pitch without using any external writing device.
