Method and apparatus for reducing oscillations excited during a seek operation in a disk drive |
摘要 |
Disk drive access times are reduced by including at least one cancellation impulse in a voice coil motor input signal to effectively cancel oscillations caused by natural resonances in an actuator assembly during a seek operation. Each cancellation impulse has an amplitude and application time that is tailored for optimal cancellation of oscillations. The amplitude and application time are calculated based upon known or estimated characteristics of the natural resonance within the actuator assembly.
