摘要： Embodiments of the invention reduce the noise occurring when the lubricating layer on the magnetic disk is smoothed. In one embodiment, a magnetic disk drive has a read/write mode parameter table for generating an electric current to be supplied to a voice coil motor when the magnetic head performs data read/write operations on the magnetic disk. The magnetic disk drive also has a smoothing mode parameter table for generating another electric current to be supplied to the voice coil motor when neither a data read nor a write operation is performed on the magnetic disk. The CPU refers to either the read/write mode parameter table or the smoothing mode parameter table and controls the electric current to be supplied to the voice coil motor. When a lubricating-layer smoothing event occurs, the CPU refers to the smoothing mode parameter table and after generating the associated electric current to be supplied to the voice coil motor, moves the magnetic head to seek between the outermost and innermost tracks on the surface of the magnetic disk to perform a smoothing process for the lubricating layer.

摘要： A semiconductor laser includes an active layer formed on a substrate and a pair of cladding layers sandwiching the active layer. On at least one of resonator end faces of the semiconductor laser, a first dielectric film with hydrogen added therein is provided. Between the first dielectric film and the resonator end face, a second dielectric film for suppressing the diffusion of hydrogen is provided. Even when a semiconductor laser with an end face coating film including a hydrogen-added film is exposed to high temperatures, peeling of the end face coating film and deterioration of the end face coating film can be suppressed.

摘要： Detection capability of a servo timing mark (STM) is improved. Long STM is configured by pseudo-STM forming part of an AGC/PLL pattern and intrinsic STM. When a system can not recognize the intrinsic STM, it keeps a state that a sector detection window is opened, and is operated in a long STM detection mode to recognize the long STM, thereby generates an STM detection signal. After the STM detection signal has been generated, an STM detection window is closed, and the system is operated in an intrinsic STM detection mode. Since the long STM has longer bit length than the intrinsic STM, it has high discriminating power with respect to other bit patterns. Therefore, even if the sector detection window is remained to be in an opened state, bit strings of data sector, address information in a servo sector or the like is not falsely recognized.

摘要： Embodiments of the present invention provide a disk drive capable of reducing, by means of simple control, vibrations applied to the drive and vibrations occurring in the drive, and a control method for controlling the disk drive. In one embodiment, a servo system comprises a sensor unit for detecting vibrations, a correction signal generator for, when the sensor unit detects vibrations, generating a correction signal, a position error signal generator for generating a PES signal on the basis of servo data read out from a disk and a target position, a servo controller for generating a servo control signal for controlling a position of a head on the basis of the PES signal, and a servo controller for generating a driving signal on the basis of the correction signal and the servo control signal. The correction signal generator includes a plurality of filters, each of which eliminates vibrations in each different frequency band, the correction signal generator selecting one or two or more RV-FF filters when vibrations are detected, and then generating a correction signal so as to reduce a position error indicated by the PES signal.

摘要： Embodiments of the invention provide control of a disk data storage device to prevent off-track writing. In one embodiment, the SA acquires the CYLIDs and ADC Values generated from the SERVO SIGNALs acquired previously, and generates DACOUT which defines a driving current of the VCM driver. The SA monitors the DACOUT generated and determines whether the DACOUT is within a predefined range. If the DACOUT is outside the predefined range, data writing is inhibited. By monitoring the DACOUT, it is possible for the VCM driver to detect supply of an overcurrent to the VCM driver 210 beforehand, and off-track writing can thus be prevented.
