New method of detecting a small reflectivity change in an optical disk surface

Abstract

We propose a new method of detecting a small change in the reflectivities in an optical disk surface. This method can be applied to the reading head of an optical disk system, and by using it, a very small reading head becomes possible. The method is based on the principle of the diode pumped solid state laser.
