Publication number: 20110078712Abstract: A spindle motor for an optical disc drive complements a loss of a function of automatically correcting a center of the spindle motor that may occur due to an excessive centrifugal force of an optical disc that is generated as the rotation speed of the spindle motor is increased. A conic outer circumferential surface of a slide cone closely contacts an inner circumferential surface of the optical disc so that a center of the optical disc is the same as a rotational center of the spindle motor The slide cone is cup-shaped so that the slide cone vertically slides in the direction of the rotation shaft. A cone yoke exerts a force to push the slide cone upwards in an axial direction so that an attractive force is used between the yoke and a magnetic cone yoke or an attractive force between the magnetic cone yoke and a clamp magnet.Type: ApplicationFiled: December 2, 2009Publication date: March 31, 2011Inventors: Euihyun Kim, Jeonggoo Kim, Youngbok Yu
