Magnetic Tape Characterization by Scanning Electron Microscope.

Abstract

An experimental program was undertaken to assess the suitability of the scanning electron microscope (SEM) for the determination of magnetic tape quality. The immediate objective of the program was to demonstrate the usefulness of the SEM as a tool for investigating four specific characteristics of magnetic tape. These characteristics were: (a) Large-scale variations in the tape front surface; (b) small-scale variations in the tape front surface, indluding the fine structure and discontinuities; (c) the areal distribution of magnetic particles; and (d) the distribution in depth of magnetic particles within the oxide coating.
