摘要： The data possessed by a parent hard disk drive is exported to a baby hard disk drive, which is connected to the parent hard disk drive, and thus, the baby hard disk drive executes by itself an optimization/inspection process including writing of servo information. A hard disk drive is reproduced by incorporating “DNA” used for reproduction into each hard disk drive, and then, by performing self-optimization and/or self-inspection by a new hard disk drive (baby hard disk drive), according to information supplied by a finished hard disk drive (parent hard disk drive).

摘要： A method and apparatus to provide a retract circuit that can correspond to the tendency toward miniaturization and low supply voltage. When drive supply voltage Vcc is applied, a retract circuit charges a retract condenser Cr with boosted voltage Vup, equal to three times Vcc, generated by a booster circuit. Then, if the drive supply voltage Vcc is cut off and a VCM driver stops, the retract circuit detects power-off with a power OFF sense circuit, and provides retract delay time by a retract delay circuit. Furthermore, when the retract delay time elapses after the drive power supply is turned off, the retract driver switches the switching circuits on, discharges the retract condenser, charged at the boosted voltage, supplies discharge current to a voice coil, and retracts the head assembly.

摘要： The present invention relates to an inertial latch mechanism of an actuator of a thin disk drive device. An inertial latch mechanism comprises a latch lever rotatable on a pivot from a release position to a latch position, and an inertial lever which is rotatable on a pivot and has a moment of inertia larger than that of the latch lever. The inertial lever rotates counterclockwise when a counterclockwise shock is given to the actuator, and pulls the latch lever at a first latch part by a first latch projection to move the latch lever to the latch position. The inertial lever also rotates clockwise when a clockwise shock is given to the actuator, and pushes the latch lever at a second latch part by a second latch projection to latch the actuator which has bumped against a crash stop and is reversely rotating.

A magnetic disk, in this regard, includes a data region having a plurality of tracks. The magnetic disk also includes a plurality of servo bursts patterned in the magnetic disk at a plurality of locations in each track. The servo bursts are operable to direct a controller to center a write head over a track in the data region and write a track identification. The servo bursts include magnetic lands and nonmagnetic grooves. The magnetic lands of the servo burst are generally configured with a uniform polarity of magnetization and a first uniform width. The nonmagnetic grooves are configured with a second uniform width.

摘要： A file is transferred directly between a parent magnetic-disk device and a child magnetic-disk device. In one embodiment, a parent magnetic-disk device has a host-mode execution program, whereas a child magnetic-disk device is capable operating in a device mode as is the case with an ordinary magnetic-disk device. The parent magnetic-disk device has an operating-mode-setting unit including a special-purpose jumper block. An MPU employed in the parent magnetic-disk device executes the host-mode execution program to put the parent magnetic-disk device in a host mode. At an activation time, the MPU refers to the logic of the special jumper block to start an operation in the host mode. The MPU controls the parent magnetic-disk device to directly transfer a file to the child magnetic-disk device. Thus, the file can be transferred between the parent and child magnetic-disk devices without intervention by a host computer.
