するデイスク駆動装置。 The screw shaft includes a screw shaft having a helical groove on the outer periphery, a stepping motor for rotating the screw shaft, and an engaging element that is slidably fitted into the helical groove. In a device that is transferred in the axial direction as the carriage rotates, the abutting piece provided on the carriage connects to the circumferential groove formed in the screw shaft in the area located in the non-recording/reproducing area, and when the power is turned off. 1. A disk drive apparatus comprising: control means for driving the stepping motor so that the head moves to a non-recording/reproducing area of a recording medium.
