Abstract

A numerical algorithm for the computation of the temperature profile induced by a pulsed laser beam has been developed by means of the quasi-implicit technique. In this calculation the effect of the latent heat of fusion was included in the temperature calculation. Some examples are given to demonstrate the utility of the numerical technique for calculating temperature profiles in optical recording media. The effects of various thermodynamic properties of recording media are apparent in the examples presented in this work, and the result of the calculated temperature information can be readily applied to the study of the writing mechanism. Extensions to a multilayered thin film system can be easily done simply by modifying the matrix elements which involve the interfacial layers.
