する磁気デイスク装置において、 前記多相ステツピングモータのそれぞれの固定
子巻線に、当該固定子巻線を回転子の駆動力とし
て作用しない程度に常に励磁させる通電回路を接
続したことを特徴とする磁気デイスク装置。[Claims for Utility Model Registration] In a magnetic disk device using a multi-phase stepping motor as a head drive mechanism, each stator winding of the multi-phase stepping motor is connected to a drive mechanism for a rotor. A magnetic disk device characterized by being connected to a current-carrying circuit that constantly excites the magnet to the extent that it does not act as a force.
