Disk drive employing digital accumulators to limit velocity and/or acceleration of microactuator |
| 摘要 |
A disk drive is disclosed comprising a microactuator configured to actuate a head over a disk, and control circuitry comprising a first digital accumulator responsive to a first register. The first digital accumulator generates at least one of a velocity command and a position command for the microactuator, and the control circuitry configures the first register in order to limit at least one of a velocity and an acceleration of the microactuator. |

1. A disk drive comprising:
a disk; a head; a microactuator configured to actuate the head over the disk; and control circuitry comprising a first digital accumulator responsive to a first register, wherein:
the first digital accumulator is configured to generate at least one of a velocity command and a position command for the microactuator;the control circuitry is configured to program the first register in order to limit at least one of a velocity and an acceleration of the microactuator; andthe first digital accumulator is further configured to integrate a first value based on the first register. |
