Servo system for a magnetic disk file. |
摘要 |
<p>A servo system for a magnetic disk file having a voice coil motor (VCM) actuator generates a position error signal (PES) from servo information recorded on one of the disks. An electrical model of the VCM is employed through which a measure of the VCM electrical current is passed to generate a simulated PES signal which is continuous even if the regular PES is sampled or intermittent.</p> |
