A support for a flexible magnetic recording medium made of a polyimide film obtained by coating a solution of a solvent-soluble polyimide resin on a solid substrate having a smooth surface, removing the solvent, and then peeling apart a coated film from the substrate. The support has high heat resistance and has a smooth surface, and a magnetic recording layer having high surface smoothness can be effectively formed thereon by a vacuum film-forming method such as sputtering.
一种用于柔性磁记录介质的支架,由聚
酰亚胺薄膜制成,该薄膜是通过在具有光滑表面的固体基底上涂布溶剂型聚
酰亚胺树脂溶液,然后除去溶剂,再从基底上剥离涂布薄膜而获得的。该衬底具有高耐热性和光滑的表面,通过溅射等真空成膜方法可在其上有效地形成表面光滑度高的磁记录层。
