  • Micro-actuator enabling single direction motion of a magnetic disk drive head
    Patent number: 8643980
    Abstract: A magnetic recording device comprises a slider body having a slider interface surface and a magnetic transducer having a lower surface coplanar with an air bearing surface of the magnetic recording device. The magnetic transducer has a transducer interface surface perpendicular to the air bearing surface The magnetic recording device further comprises a piezoelectric actuator operably connecting the slider interface surface and the transducer interface surface. The piezoelectric actuator is configured to translate the magnetic transducer with respect to the slider body in a direction substantially parallel to the slider and transducer interface surfaces. The piezoelectric actuator comprises a plurality of elongate flexures disposed in parallel planes within a body of the piezoelectric actuator.
