Abstract

Essential peculiarities of the readout procedure of the optical disc with the dye active layer are determined by the coating process technique and by the active layer optical parameters. Such active layers have a mixed amplitude-phase microstructure. There is an inherent problem in continuous- groove servo system that embossed and information pits degrade servo signals generated by grooves, and thus also degrade fast and reliable read/write. To solve this and related problems, the present paper uses a two-dimensional scalar diffraction model to simulate optical servo signals such as the tracking error signal (TES) and the sum information signal (SIS). The present paper describes the optimum geometry of an optical disc with embossed and read- only data pits and continuous grooves and also optimum thickness of active layer.
