Abstract:
A magnetic disc apparatus includes a micro actuator for two-stage actuator having a first stage and a second stage, and a slider mounted to the miro actuator and having a head element to perform recording and reproduction into/from a magnetic disc. A thermal actuator and a spring part are provided on a table, on which the slider is put. The thermal actuator is connected to the slider, and the thermal actuator includes a V-shaped thin film resistance.
