Two methods are developed to determine the crystallization parameters of phase change materials on mark formation in phase change optical recording. Both methods are based on the comparison of experimental and numerical modeling results. In the first method, the shape of short written marks is compared in experiment and simulation. In the second method, long marks are partially erased. The resulted mark shape reveals information on the crystallization parameter. The set of crystallization properties in the simulation that gives the best match between experimental and numerical results can describe the crystallization behavior of the phase change material. The determined crystallization parameters and model give excellent predictions on mark formation and erasure in growth-dominated phase change materials.
This paper gives a brief introduction of the generic disc concept in the introduction section. Then a detailed description of the system architecture, software architecture, player flowchart and application software flowchart are provided in the rest of this paper.
