摘要： A hybrid storage device that includes a hard-disk drive (HDD) and a flash memory is described. When control logic in the hybrid storage device receives a request from an external device to write a block of data to a logical address in a first portion of an address space that maps to the HDD, the control logic writes the block of data to the HDD. However, if there is a change in environmental state information of the hybrid storage device during the write operation, the control logic writes at least a portion of the block of data to a logical address for the block of data in a second portion of the address space which maps to the flash memory. Note that the address space may be common to the external device and the hybrid storage device.

摘要： A hard disk drive protection grip pad which provides a physical and active method of inhibiting portable or desktop disk drive from free falls or dropping the drive. This active method prevents and protects the disk drive from damage of physical impact on free falls or dropping of drive, thus preventing damage to internal components in the disk drive, which in most cases lead to unrecoverable loss of data storage.

摘要： A method implemented in a storage system that has moveable storage devices includes a motion controller receiving movement related data of a storage device from at least one sensor associated with the storage device. In response to the received movement related data indicating at least one pre-identified condition, a park command is issued that triggers the reading head of the storage device to enter a parked state in which the storage device is protected from damage that can occur due to motion of the reading head while the pre-identified condition exists.

摘要： A disk drive is disclosed comprising a timing loop configured to generate a clock synchronized to a rotation of a disk and a servo loop configured to control an actuator to actuate a head over the disk. A timing signal generated by the timing loop is filtered with a pre-compensation filter (PCF) comprising an inverse transfer function from a delta in a rotation velocity of the disk (Δω) due to a vibration affecting the disk drive to the timing signal, and the actuator is controlled to actuate the head over the disk based on an output of the PCF.

摘要： In response to positioning a read/write head of a hard drive, a voice coil motor (VCM) input signal is applied to a voice coil motor and a microactuator (PZT) input signal is applied to a microactuator. A position signal is determined in response to positioning the read/write head. A PZT component is decoupled from the position signal to determine an estimated VCM response. The estimated VCM response used to determine an estimated VCM disturbance. A VCM component is decoupled from the position signal to determine an estimated PZT response. The estimated PZT response used to determine an estimated PZT disturbance. The VCM input signal and the PZT input signal are modified respectively to compensate for the estimated VCM disturbance and the estimated PZT disturbance.
