Abstract: When the magnitude of a traverse signal exceeds a predetermined level, the value of a microstep drive signal is changed by one microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases. A determination is made as to whether or not the magnitude of the traverse signal becomes a predetermined level or less. When the magnitude of the traverse signal does not become the predetermined level or less, the magnitude of the microstep drive signal is returned to the pre-change value and the value of the microstep drive signal is incremented by an additional microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases.

Abstract: An optical disc reproduction apparatus is provided for permitting appropriate automatic adjustment to a servo control system, particularly a CD and a DVD-ROM having a BCA. A limit switch 24 is disposed in such a manner that it detects movement of an optical pickup 11 to a position which is located at a radius of 23.49 mm from the center. A system controller 22 moves the optical pickup 11 by 1.0 mm in an outer radial direction from the position detected by the limit switch 24, and reads a signal from an optical disc 5 at that position to carry out the automatic adjustment to the servo system, through a servo controller 21 and a feed motor 18. As a result, in the CD, a signal within a lead-in area thereof is used for and subjected to the automatic adjustment performed by the servo controller 21, while in the DVD-ROM, a signal in an outer peripheral area of a lead-in area having the BCA and in the vicinity thereof is used for and subjected to the adjustment.
