Abstract
A read/write head microactuator includes first and second insulating deposits that are flat, spaced apart by an air gap, and laterally movable responsive to a microactuator electrical drive current. First and second flat, interdigitated drive electrode deposits are deposited on the first insulating deposit. A flat, digitated sense electrode deposit is deposited on the second insulating deposit. The sense electrode deposit provides a relative position output. The sense electrode deposit faces both the drive electrode deposits across the air gap.
