Abstract

We present simulations and experimental results on encoding information both in the longitudinal and transverse directions of an optical beam reflected from an asymmetric pit. The method does not require interferometric detection but is based on intensity measurements using a simple quadrant detector. In addition, we also discuss the implementation of this scheme in an optical recording setup and make an analysis of the crosstalk between neighboring pits.
