Paper Abstract

In the optical data storage technology the optical servo crosstalk represents an undesired phenomenon. The optical crosstalks between the tracking push-pull and focus error signals are analyzed for various focusing techniques. The conditions minimizing these crosstalks are drawn. It is also shown that a simple far field diffraction method can be used for the evaluation of the focus error signals which are detected in the Fresnel dif-fraction domain.
