This paper describes a computer simulation model of an optical disc memory. Read/Write system modeling of an optical memory storage device must include all parameters that affect pit formation (the write process) as well as the quality of the playback signal (read). The model includes parameters for the read and write electronics, optics, and the media. It will be shown that the model can incorporate specifics such as acousto-optic modulator rise times, lense aberrations, and pit size variation. Results of a sensitivity study for one variable will be presented.
