摘要： A voice coil motor capable of quickly and precisely positioning a magnetic head with high precision is provided with a bearing rotatably supporting a head carriage without being influenced by a radial load. Two coils having radial sections contributing to generate a torque are provided to be rotatable in a magnetic space formed by a permanent magnet and a pair of yokes, and are layered along a central rotating axis in such a manner that an extension angle of the radial sections of one coil differs in direction from that of the radial sections of the other coil. When electric current flows, no radial load works, and a resultant force generated in these coils can be a couple of forces in the direction vertical to the movement direction of the magnetic head, so that the magnetic head can be quickly positioned with high precision, realizing a small magnetic disk device.
