Metal thin film magnetic recording medium |
摘要 |
The present invention provides a metal thin film magnetic recording medium in which an underlying Cr layer, a magnetic recording layer and a protection layer are laminated in this order on a non-magnetic medium substrate. The medium substrate comprises an NiPX layer laminated in this order on a non-metallic base plate such as a glass base plate or a carbon base plate. X is one or mope elements belonging to a group of 4, 5 and 6 in a periodic table, and the content X is less than 20 at % in total. A heat accumulating non-magnetic layer having excellent heat conductivity may be formed on the non-metallic base plate and laminated between the NiPX layer thereon.
