摘要
A microactuator comprises a stator, a rotor and an operator coupling the rotor to the stator. The operator comprises a four-block magnet array supported by either the stator or rotor, and first and second coils supported by the other of the stator or rotor. Current in one coil alters magnetic flux linkage to move the rotor along a first axis. Current in the other coil alters magnetic flux linkage to move the rotor along a second axis orthogonal to the first axis. The microactuator is applied to the slider of a disc drive to position the head at a selected flying distance adjacent the disc medium, and to position the head relative to a track on the medium.
