<p>An aromatic polyamide film for high-density magnetic recording medium which is excellent in electromagnetic transducing characteristics even when used as a base film of a deposited metal thin film magnetic recording medium, suffers from few dropout, and enables production of a large-capacity magnetic recording medium. The film has both excellent surface flatness and excellent transportability especially useful for high-density magnetic recording medium and meets simultaneously two contrary characteristics: the ability of preventing troubles such as push-up by projections at the calendering step and good rollability.</p> |
