Abstract
Disclosed is a disk rotating mechanism equipped with an automatic aligning mechanism in which the number of parts is reduced and in which an improvement in assembly operability and a reduction in cost are achieved. The automatic aligning mechanism includes a case body made of a non-magnetic material and formed as a flat cylinder with one end surface closed, two or more balance members provided so as to be freely movable in the inner space (movement space) of the case body, and an attracting magnet adapted to attract the balance members when the rotating mechanism is at rest or rotating at low speed, wherein the case body is supported by the spindle shaft of a spindle motor and wherein the closed end surface (table portion) thereof serves as the table portion of a turntable.
