Two-degree-of-freedom control scheme for flying-height and tracking-position controls with thermal actuators in HDDs
To improve positioning accuracy of a magnetic head in hard disk drives (HDDs), a triple-stage-actuator system was proposed with a thermal positioning actuator for a magnetic head positioning system. This positioning system has three types of actuators: a voice coil motor (VCM), piezoelectric (PZT) a...
