Abstract
Single layer (≃ 300A thick) Te and Te-alloy films on polymethylmethacrylate substrates are widely studied for possible use as optical recording media. The ablative hole formation process in such media is however still poorly understood. In this paper, data is presented to show that ablative writing in Te-alloy films has two hole opening regimes. This two regime hole opening process is shown to lead to a qualitative understanding of the contrast ratio versus writing laser power characteristics of Te-alloy films.
