Abstract (en)
[origin: WO9319462A1] A magnetic recording medium, such as a tape or a floppy disc, can be 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 may be deposited upon the substrate at high temperature.
