Paper Abstract

This report introduces a New Tracking Technique that extends the radial tracking range to more than several tracks. This New Tracking Technique is a major improvement in the tracking servo's response to mechanical disturbances such as shock and vibration. An added closed loop Quadrature servo conditions the tracking error signal to provide a continuous negative feedback tracking signal over several tracks. This report also describes the ease with which this Quadrature servo is incorporated into current optical disc products and the many advantages offered by its use in optical disc products.
