FIG. 1 is a schematic diagram showing an embodiment of the present invention. 2 and 2' are rotating shafts, 3 is a rotating plate, 4 is a light emitting element, 5 is a light receiving element, 7 is a magnetic head, and 9 is a magnetized medium.
Claims (1)
刻んだ回転板と該回転板を挾んで位置する受発光
素子と回転板の回転によりスリツトの作用で断続
的に光を受ける受光素子からの信号に同期してパ
ルス電流が流れる磁気ヘツドを備え、前記回転板
の回転軸と連結した回転軸に同軸に保持した被着
磁媒体の着磁面に前記磁気ヘツドを相対させた多
極着磁装置。 A rotating plate with slits radially carved at predetermined intervals around the rotation axis, a light receiving/emitting element located between the rotating plate, and a signal from the light receiving element which receives light intermittently due to the action of the slits due to the rotation of the rotating plate. A multi-pole magnetizing device comprising a magnetic head through which pulsed currents flow in synchronization, the magnetic head being opposed to a magnetized surface of a magnetized medium held coaxially with a rotating shaft connected to the rotating shaft of the rotating plate.
