ABSTRACT:
A disk device has a small size, a small thickness, a high efficiency, a small degree of vibration and a small level of noise. In one embodiment, the disk device comprises a disk for storing information and a disk drive for driving the disk. The disk drive includes a rotor portion mounting an annular permanent magnet on the outer peripheral portion thereof, and a stator portion disposed on the outer side in the radial direction of the annular permanent magnet. The stator portion is constituted by a wiring board provided with a stator core formed by laminating magnetic metal plates in a radial manner and a coil that is so formed as to surround the stator core while electrically connecting wiring layers and through hole portions. The coil is so formed that among the envelopes connecting the outermost peripheral surfaces of the coil in the radial direction, the neighboring envelops and intersect at an inner position in the radial direction.
