The design and evaluation of optical recording systems, media, and codes require both qualitative and quantitative understanding of the readout process. Scalar diffraction theory permits a simple formulation of the readout process, which provides a qualitative insight and also permits rapid, detailed, numerical solutions to a wide range of problems. Several examples demonstrate the application of the model to Laser Write and Read (LWR) optical recording media.
