ABSTRACT:
The rotary actuator comprises sector-shaped magnets, with a coil located therebetween. A flexible printed cable is fixed on one surface of the coil, and opposes the magnets. The flexible printed cable extends inside the coil. The innermost end of a conductive wire constituting the coil is connected to the flexible printed cable inside the coil, without being guided between the coil and the magnets. Power is supplied to the coil through a cable located between the coil and the magnets. The coil generates a magnetic flux in response to the input current. A force acts on the coil by way of an interaction between the magnetic flux from the coil and the magnetic flux from the magnets. For this reason, the coil rotates about a rotating shaft of a head-support mechanism mounted on the coil. The head is then moved and positioned at a target track.
