The manufacturer of the optical disc drive needs a more; teH k problem. The purpose of the present invention is to provide a spindle axis disc bearing mechanism: a pre-axis tilt adjustment mechanism that uses planes to be parallel to each other. The plane and the optical head module Another object of the present invention of a substrate assembly is to connect an optical head module substrate Achieve ^ plane ^ tilt adjustment method, used to determine the plane of the substrate so that the spindle motor disc bearing "set-up: axis motor fixed head module substrate parallel. The plane and optical reading and writing of the oxygen carrier disk According to the above purpose of the present invention, it is used for an optical disc reading device.
