Magnetic recording medium |
摘要 |
The present invention discloses a magnetic recording medium comprised by sequentially layering a magnetic recording layer, intermediate layer and concealment layer on a non-magnetic substrate made from a thermoplastic resin, wherein the surface of the intermediate layer forms a single smooth surface with the surface of the non-magnetic substrate as a result of embedding the magnetic recording layer and the intermediate layer within a portion of the non-magnetic substrate, and the concealment layer conceals the surface of the intermediate layer and the surface of the non-magnetic substrate. This magnetic recording medium has superior concealment and adhesion of the concealment layer for the magnetic recording layer as well as a high level of design properties regardless of the type of magnetic particles used in the magnetic recording layer.
