囲第１項記載の磁気デイスク用アクチユエータ。[Scope of Claim for Utility Model Registration] (1) A magnetic circuit formed by fixing a yoke to one side of permanent magnets with different polarities and making the permanent magnet surfaces face each other, a moving coil at one end and a magnetic head at the other end. In the actuator for a magnetic disk, the actuator is composed of arms that are fixed to each other so as to be swingable, and a movable coil is disposed in the gap of the magnetic circuit. What is claimed is: 1. An actuator for a magnetic disk, characterized in that: a permanent magnet is fixed thereto, and a detection coil is provided to cross the magnetic flux of the permanent magnet and is swingable in cooperation with the arm. (2) The actuator for a magnetic disk according to claim 1, wherein the permanent magnet is a rare earth magnet and the other permanent magnet is a ferrite magnet.
