A flexible magnetic recording medium containing polybenzazole polymers (flexible mag-netic rocording medium containing polybenzazole polymers)

摘要

Magnetic recording media such as tapes or floppy disks are prepared using substrates of high modulus polybenzazole polymer films. Suitable films can be sified from an anisotropic polybenzazole dope. A continuous layer of a magnetizable material is deposited on the substrate at a high temperature.
