    摘要: Disclosed are various systems, methods, and programs embodied in a computer readable medium for calibration of a lens position in an optical disc drive. In one embodiment, a method is provided that comprises manipulating a lens focus actuator to relocate the lens from a first position to a second position. The lens substantially focuses a laser onto the surface of the optical disc when in the second position. The method also comprises determining a first input setting delta to the lens focus actuator that corresponds to a predefined position offset of the lens. The first input setting delta is determined based upon a second input setting delta corresponding to a distance between the first position and the second position.

    摘要: An optical pickup unit (OPU) includes a moveable structure that is moved by a voice coil motor component in response to an input signal. The moveable structure includes a pattern that is moved corresponding to the input signal. An encoder reads the pattern to generate an output signal that corresponds to pattern movement as the input signal is applied over a period of time. A controller calculates a calibration factor relating the pattern movement to the input signal.
