Disk drive actuating first head microactuator while sensing signal from second head microactuator

摘要

A disk drive is disclosed comprising a first disk surface and a second disk surface, a first head operable to be positioned over the first disk surface, a second head operable to be positioned over the second disk surface, a first microactuator operable to actuate the first head, and a second microactuator operable to actuate the second head. The first head is actuated over the first disk surface using the first microactuator while processing a second sensor signal generated by the second microactuator, and the second head is actuated over the second disk surface using the second microactuator while processing a first sensor signal generated by the first microactuator.
