Magnetic recording medium.

摘要

A magnetic recording medium (10, 13, 15, 17, 19, 21) having a substrate (8) and a vertical magnetization film (9, 12, 14, 16, 18, 20) formed on the substrate(8). The vertical magnetization film (9, 12, 14, 16, 18, 20) is composed of an artificial superlattice (9a, 12a, 14a, 16a, 18a, 20a) and a thin film (9b, 12b, 14b, 16b, 18b, 20b) alternately deposited on the substrate (8). The artificial superlattice is a Co/Pt or Co/Pd artificial superlattice which is composed of alternate Co and Pt or Pd layers deposited on the substrate. The thin film is a Pt or Pd or Co thin film. The vertical magnetization films present lower Curie points, higher residual flux densities and higher coercivity. By using the recording medium to thermo-magnetic printers, for example, a higher resolution and a smaller power consumption can be achieved. <IMAGE>
