AbstractCrosstalk in the readout channel of a data storage system is obtained by a linear decomposition of the reflected field from the optical disk according to Babinet's principle. Crosstalk is the jitter introduced into the readout signal. Also, the formation of the exit pupil irradiance is described heuristically as the combination of fields in a three beam interferometer resulting from the Babinet decomposition of the reflected disk field. Three detector patterns result. The properties of the detector patterns are affected by media parameters. The media parameters are the reflectivity function of the disk and the depths of the tracking grooves. The detector patterns are also affected by the aberrations introduced into the read laser beam. This dissertation provides a complete description of crosstalk and the detection process in optical data storage systems.
