Paper Abstract

Correcting disk tilt aberrations have been studied extensively in recent years. One example is using LCD phase shift modulating devices. Another example is using a comatic lenses. The other example is combined tracking position and tilt sensor for actuator. Method 1 has the advantage ofless space, lower cost; but disadvantage of low wavefront resolution. Method 2 and 3 has the disadvantage of precise mechanical control.
