Authors: Woodward, J. G.; Coutts, M. D.; Levin, E. R.

Abstract

The scanning electron microscope (SEM) has only recently become generally available as a commercial device. The combination of high resolution and high magnification with a remarkable depth of focus provided by the SEM, together with simple procedures in specimen preparation, make this instrument admirably suited for use in disc-recording research and development. A description of the SEM is given, and photomicrographs of details of recording and playback styli and of new and worn groove walls in records are shown.
