る磁気デイスク記録再生装置のヘツド駆動機構。[Claims for Utility Model Registration] A head drive mechanism for a magnetic disk recording/reproducing device in which a head frame on which a magnetic head for recording and reproducing signals on a magnetic disk is mounted is moved by regulating the direction of movement by a guide member. A slide guide surface is formed on the opposite side of the guide member to the magnetic head of the head frame, and the inner ring is fitted onto the slide guide surface onto a fixed shaft fixed to the main body so as to be perpendicular to the disk surface. 1. A head drive mechanism for a magnetic disk recording/reproducing device, characterized in that the outer ring of at least one ball bearing is preloaded and brought into contact with a fixed shaft in the axial direction by a preload urging means.
