Dimensionally-stable polymer film and magnetic medium using the same |
摘要 |
<p>A polymer film characterized in that the Poisson's ratio of the longitudinal direction (MD) to the transverse direction (TD) is less than 0.4. This film exhibits superior dimensional stability under high tension, cause almost no reading errors when it is used in a magnetic recording medium, and provides a high-capacity magnetic recording medium having superior electromagnetic conversion characteristics.</p> |
