Disk drive performing lifetime logging of microactuator sensitivity |
摘要 |
A disk drive is disclosed comprising a head, a disk surface, and a voice coil motor (VCM) and a microactuator operable to actuate the head over the disk surface. A sensitivity of the microactuator is periodically measured over a lifetime of the microactuator. Each measured sensitivity is stored in a timeline log, wherein the timeline log represents a degradation curve of the microactuator over the lifetime of the microactuator. |
