Abstract

This paper reports a novel experimental method for investigating the microscopical readout characteristics of optical recording media in conjunction with optical and electron microscopy. The leaf spring-supporting guide is employed for reading out the written bit information by scanning the recording medium surface with a focused laser beam. The relationship between the readout signal wave- form and the shape and structure of the written bits has been investigated for several examples of phase change optical recording media.
