Paper Abstract
A new focus detection method based on filtering of the servo beam near the domain of frusterated total reflection is intoduced. The method naturally combines an unfocused, wide diameter servo beam with differential detection, making the focus servo of an optical drive extremely robust and dynamically stable.
