摘要： A hard disk drive, its use and production are described. A read/write disk stores digital data. A spindle motor supports the read/write disk for controlled rotation thereof. A head arrangement moves to selectively access the read/write disk in a data access mode and moves to a parked position. A dedicated input is receives a first sensor related input signal. A processing arrangement executes the data access mode by cooperatively controlling the spindle motor and the head arrangement, monitoring the sensor related input signal for a predetermined characteristic thereof, and responsive to detection of the characteristic, at least moves the head arrangement to the parked position. A hard disk drive multi-sensor group, monitoring technique and interface are described.

摘要： The present invention relates to a system for determining whether the flying height of a read/write head above a disk in a disk drive is within an acceptable range, in substantially real time. The system relies on variations in read signal resolution with flying height to make the determination. In one embodiment, read signal resolution is measured and compared to a predetermined threshold value to determine whether the present flying height is in the desired range. In another embodiment, the number of peaks in a read signal that are detected (and/or not detected) by a detector is used to determine whether the head is in the proper flying height range. Because of read signal resolution effects, the number of detected peaks will decrease as the flying height of the head is increased. Means are also provided for postponing a transfer of data to/from the disk when it is determined that the head is not within the acceptable range.

摘要： A disk drive system corrects run-out errors without substantial PES transients and without significant response time. The disk drive system includes a servo compensation system coupled to a read/write head. The servo compensation system is adapted to generate a run-out correction waveform for a track in a disk. The run-out correction waveform includes one or more sinusoidal component waveforms, each of which is defined by a phase and an amplitude. The method includes measuring an amplitude and a phase of one or more sinusoidal component waveforms for a set of specified tracks in a disk. The method also includes determining a phase and an amplitude of one or more sinusoidal component waveforms for a destination track based on a measured amplitude and a measured phase of the one or more measured sinusoidal component waveforms. The sinusoidal component waveforms for the destination track are adapted to substantially correct a run-out error in the destination track. The method further includes generating a run-out correction waveform for the destination track such that the disk drive system substantially corrects the run-out error in the destination track.

摘要： An electromechanical data storage arrangement is interfaced with a host. The interface may include a conductor that carries read and write gate signals. Another conductor carries both a servo sync mark and an error signal. The storage arrangement includes an external serial interface connected to a host serial interface applying a device identification to a portion of serial control-related data that travels over the interface. A serial router in the storage arrangement uses the device identification to manage the control-related data between the interface and a number of serial devices and associated interfaces within the storage arrangement. The serial router is in selective data communication with each of the device serial interfaces, for using the device identification to direct a host-asserted command to a targeted device where each device is controlled by a different command set such that the system can be customized for different command sets of different devices.

摘要： A disk drive system comprising a shock evaluator is disclosed. The shock evaluator includes a shock evaluation circuit and threshold logic and firmware that is capable of evaluating the level of physical shocks to the disk drive system. The shock evaluation circuit is capable of comparing the level of a physical shock to threshold shock values. The threshold logic and firmware is capable of periodically resetting the threshold shock values to account for the change in operating conditions experienced by the disk drive system. When the shock evaluator determines that a physical shock is present, communication between the read/write transducer and the disk is interrupted to prevent corruption of data stored on the disk.
