FLEXIBLE MAGNETIC RECORDING MEDIUM CONTAINING POLYBENZAZOLE POLYMERS |
| 摘要 |
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. |
