摘要： Commutation is the process of driving current through the windings to produce a rotating magnetic field that the rotor attempts to catch. Typically, four to six commutation cycles occur for each rotation of the rotor of the motor. Unlike traditional commutation methods where only six phases are commutated during one commutation cycle, the hybrid commutation cycle includes 12 phases. The particular method for commutation switches between current driving modes where one driving mode drives current through all three windings and an other driving mode drives current through less than all three windings of the motor. More particularly, in the second driving mode current is driven through two windings of the motor. During a commutation cycle, these driving modes are alternated.

摘要： A disk drive system for use in limited power applications is disclosed. The disk drive includes a spindle motor having two or more windings, along with a spindle motor driver which can drive the spindle motor in any of a unipolar, bipolar or tripolar mode. The bipolar or tripolar mode is used to start the disk drive and then the unipolar mode is used to operate the disk drive while data is being retrieved. By combining the three drive modes a large start current reduction and higher rotation velocities are achieved. Current consumption is further minimized by adaptively transitioning from bipolar to unipolar modes of operation. The disclosure also includes a general methodology for optimal motor K.sub.E and K.sub.M parameter selection.

摘要： A disk drive is disclosed comprising a disk, and a head actuated over the disk. Control circuitry within the disk drive is operable to write a plurality of code segments to a primary area of the disk, and write the code segments to a backup area of the disk. The control circuitry reads the code segments from the primary area of the disk and executes the code segments read from the primary area of the disk. After reading the code segments from the primary area of the disk and executing the code segments, the control circuitry verifies recoverability of the code segments from the backup area of the disk, and when the verification fails, copies the code segments from the primary area of the disk to the backup area of the disk.

The mobile device may be a hand held computing device such as a personal digital assistant (PDA) or a mobile terminal such as a cellular telephone. The mobile device includes a host processor for accessing data on the disk drive. The disk drive has a rotating disk media and a moveable read/write head disposed over the disk media.

摘要： A rotating media storage device (RMSD) to adaptively estimate a read access time to a second track based on the radial position of the second track is disclosed. The RMSD includes a disk having at least a first track and a second track and a microprocessor for controlling operations in the RMSD including seek operations. During a seek operation, the microprocessor bins a radial position of the second track and estimates a read access time to the second track based on the binned radial position of the second track.

摘要： A disk drive is disclosed for optimizing write current settings relative to drive operating characteristics and a plurality of ambient temperature readings. Test data is written to and read from the disk to generate quality metrics that are evaluated to generate an optimized write current setting for each ambient temperature reading. In one embodiment, the optimized write current settings are derived during manufacturing and used in-the-field during normal operation. In another embodiment, the optimized write current settings are re-optimized in-the-field to compensate for changes in the drive operating characteristics that occur over time (e.g., environmental changes and electrical and mechanical changes).

摘要： A spindle motor in a disk drive is driven by a driving circuit that, upon receipt of a signal or command, selectively spins up the spindle motor according to a first spin up profile or according to a second spin up profile that is defined to provide a longer spin up time in comparison with the spin up time defined by the first spin up profile. The second spin up profile spins up the spindle motor in a longer period of time and/or generates less acoustic noise as compared to the first spin up profile.
