PERPENDICULAR MAGNETIC RECORDING MEDIUM AND METHOD FOR PREPARING THE SAME |
摘要 |
<p>There are disclosed a perpendicular magnetic recording medium comprising a substrate of a polymer film containing 0.7% by weight or less of a residual solvent and a ferromagnetic alloy layer formed on the substrate and a method for preparing the same comprising the steps of heating a substrate composed of a polymer film containing a residual solvent in order to regulate a content of the solvent existing in the substrate to 0.7% by weight or less; and afterward forming a magnetic layer composed of a ferromagnetic alloy on the substrate. The perpendicular magnetic recording medium of the present invention has a prolonged durability and heightened reliability.</p> |
