摘要 |
A magnetic recording system for recording signals onto a coat-type magnetic tape using magnetic powder by using a magnetic head, and a magnetic recording system for recording signals onto a coat-type magnetic disk using magnetic powder by running a magnetic head in contact with the disk, are disclosed. The magnetic tape has a coercive force Hc of 2000 to 3300 Oe in the former system, while the magnetic disk has a coercive force Hc of 2000 to 3500 Oe in the latter system. In both systems, signals are recorded by using a magnetic head using magnetic core members having a saturation magnetic flux density of 15 kG or greater. The magnetic core member having the saturation magnetic flux density of 15 kG or greater is exemplified by a material expressed by a composition formula (Fe95.5Al1V0.5Nb0.5Cu0.5Ru2)92N6O2. <IMAGE> |
