Abstract

The author proposes a new noise power-spectrum estimation method for mark-dimension fluctuation in optical disks. Diffraction by marks was modeled using Fraunhofer diffraction theory, and mark-dimension fluctuations were taken into account through statistical averaging. The calculated and experimental results agreed well. Fluctuations in the mark edge position mainly contributed to noise.
