Disk drive with improved spin-up control |
| 摘要 |
A disk drive is disclosed comprising a head actuated over a disk, and a spindle motor operable to rotate the disk. The disk drive comprises control circuitry configured to a rotation speed of the spindle motor, generate a gain as a function of the measured rotation speed, wherein the function comprises a polynomial having a degree greater than one, and spin-up the spindle motor based on the gain. |
