Abstract:
A test device for horizontal position of an optical disc drive, comprising(a) a test platform having a plurality of vertical position rods mounted thereon and the rods being of similar horizontal height; and (b) at least a sensor mounted within the area formed by the position rods located on the platform, and including at least an emitting element and a receiving element, the emitting element emitting an optical detection signal (i.e., incident wave) to an optical disc connectedly driven by the motor rotating shaft of a pick-up mechanism to be tested, by means of a reflected optical signal produced by the optical disc, the receiving element receives the signal, and the sensor produces a horizontal height measuring data, and thereby the results and the measured horizontal height data determine whether the motor horizontal position of the optical disc drive pick-up device is parallel to the horizontal axial direction of the optical disc drive pick-up device.
