DUAL STAGE DISC DRIVE ACTUATION SYSTEM |
摘要 |
A dual-stage disc drive actuation system for positioning a transducing head over a selected track of a rotatable disc having a plurality of concentric tracks includes a low resolution actuator and a high resolution microactuator. An input circuit provides a signal corresponding to the selected track. The actuator and microactuator are then operated to position the head over the selected track. The dual-stage actuation system positions the head over the selected track without significant off-track error within about 0.5 milliseconds for a track density of at least about 12,000 tracks-per-inch.
