Magnetic recording medium and manufacturing method thereof |
| abstract |
(57) [Abstract] [Purpose] To provide a thin film magnetic recording medium having excellent recording and reproducing characteristics. A magnetic layer mainly composed of Co and oxygen in which a principal axis of magnetic anisotropy rises by 20 ° to 80 ° in one direction with respect to a surface of a non-magnetic substrate is formed, and a coercive force Hs on the film surface side of the magnetic layer is 6 The coercive force Hb on the substrate interface side is 60 It is less than 0 Oe. Such a medium is obtained by subjecting the surface of the non-magnetic substrate to plasma treatment in an inert gas or oxygen gas atmosphere, After that, while introducing oxygen gas into the film forming atmosphere, C It can be produced by depositing an alloy mainly composed of o on the surface of the plasma-treated non-magnetic substrate. |
