To provide a simple and inexpensive actuator mechanism for a magnetic disk drive, wherein the actuator mechanism includes an approximately circular coil and a simple shaped magnet, and is capable of displaying adequate performance required for the magnetic disk drive.
The magnetic disk drive includes an actuator mechanism which has an approximately circular coil and an approximately rectangular magnet. The long axis direction of the rectangular magnet is oriented in parallel to a straight line connecting the center of the inner circle of the circular coil in a state in which the actuator is positioned at the outermost circumference of a data area and the center of the inner circle of the circular coil in a state in which the actuator is positioned at the innermost circumference of the data area.
