摘要： A magnetic disk device (10) comprises a magnetic disk (11) in which a data zone (32) is formed. An actuator (22) has a voice coil (51) and a head slider (14) carrying a magnetic head, the actuator (22) being swung to move the magnetic head over the disk (11) between an innermost position (Pi) of the data zone and an outermost position (Po) of the data zone. A magnet has a magnetization center (58) and is opposed to the voice coil so that a voice coil motor (23) which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center (C) of the voice coil (51) from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.
