摘要： A magnetic recording medium, such as a tape or a floppy disc, is made using a substrate of high modulus polybenzazole polymer film. Suitable films can be coagulated from anisotropic polybenzazole dopes. A continuous layer of magnetizable material is deposited upon the substrate at high temperature.
