摘要： A head driving apparatus has two yokes each having two generally parallel members which extend respectively in the direction generally perpendicular to the optical axis of a lens, and the yokes are disposed on both sides of the two side surfaces of the head. Two tubular head driving coils are fixed to the head and externally fitted on the member of each yoke, which is nearer to the head. At least a first magnet is fixed to the member of each yoke lying further from the head. A plurality of second magnets are fixed to the head and oppose the first magnets. The head is supported in a non-contact state by the repulsive forces of the first magnets and the second magnets, and the head is driven by energizing the head driving coils. An optical disk apparatus is equipped with the head driving apparatus.

摘要： According to one embodiment, a disk storage apparatus includes a write module and a controller. The write module is configured to move a write head over a disk, and to perform the shingled write method, recording data in the first track while erasing data from a part of the second, i.e., adjacent track. The controller is configured to acquire a first head positioning error with respect to the first track and a second head positioning error with respect to the second track. If the first head positioning error exceeds an off-track threshold value, indicating that the data may no longer be maintained in the first and second tracks, the controller inhibits the data writing.

摘要： According to an aspect of the embodiment, in a magnetic recording apparatus having a magnetic recording medium of a patterned media system, a voltage generated between both terminals of a magnetic field generating coil in a case that a DC current is supplied to a recording element of a magnetic head is measured by a voltage measuring circuit in order to perform accurate recording at the center of each of magnetic body regions sectioned with non-magnetic body regions. Based on the measured voltage, a change in coil inductance in passage of the magnetic head over a magnetic body region and a non-magnetic body region in a patterned media is detected by a voltage change detecting circuit. A write clock signal which synchronizes with the change in coil inductance is generated by a clock signal generating circuit.

摘要： In the case of a magnetic head tracing a record track from the left to right, a positional demodulation signal obtained by passing a first servo sector existing in the record track is minutely corrected by a positional correction signal converted from a phase shift amount which is obtained by sequentially passing at least plurally placed correction areas, thereby becoming a positional signal, followed by obtaining a positional modulation signal in the same manner at a second servo sector existing in the record track subsequently traced, and further minutely corrected by a positional correction signal obtained by passing similar plural correction areas arrayed at discretionary intervals starting from the second servo area. Such minute correction operations are performed for one circumference of a track, which is continued for carrying out an accurate positioning trace to a target track.

摘要： The present invention realizes stable focus entry control even in the case where a wideband focus error signal is used with which the focus error signal sensitivity and the level in the vicinity of a focus point vary depending on a light path length. A second focus error signal having a wide range is used, causing an objective lens to approach a disk while maintaining a predetermined rate of change with respect to time, and, during approach, a transition to focus servo is performed by detecting the focus position according to the first focus error signal.
