Abstract
The present invention provides a disk apparatus and a motor therefor that require low power consumption and reduce errors during recording or reproduction by damping vibration, preventing the motor from falling toward a head. In a disk apparatus comprising a motor and a head, the motor has a rotating portion and a fixed portion, the rotating portion of the motor has a device for holding a disk, the fixed portion of the motor has a bearing section and a stator section mounted in the disk apparatus via damping members, and the damping members are provided in such a way that one side of these members which is closer to a line joining the motor with the head has a higher rigidity than the other side.
