Abstract

Certain seek techniques were developed for the Optotech 5984 drive to accommodate the use of a stepper motor coarse actuator and a hardware environment designed to minimize complexity and to achieve a low-cost end-unit goal. Of these techniques, the following will be discussed: fine seek actuation offset compensation, and velocity control in fine seek actuation. The fine seek actuation offset compensation provides necessary correction to fine seek drive values due to the effects of the limited positioning resolution of the stepper motor coarse actuator. The velocity control technique developed for fine seek actuation provides sufficient velocity control at track crossing frequencies up to 15Khz using a relatively slow, low-cost microprocessor.*
