| titleOfInvention | Magnetic recording medium |
| abstract | PURPOSE: To obtain the magnetic recording medium which is of a thin film type of a continuous film, has the magnetic characteristics equiv. to or better than the magnetic characteristics of metallic materials and has the chemical stability equiv. to or better than the chemical stability of iron oxide by forming micrograin boundaries to the thin film contg. Fe 3 C or Fe 5 C 2 or Fe 2 C or the plurality thereof as essential components. n CONSTITUTION: This recording medium is formed of the film having ≥4,000e coercive force among the thin ferromagnetic films contg. the Fe 3 C or Fe 5 C 2 or Fe 2 C or the plurality thereof as the essential components. Namely, the micrograin boundaries are formed to the thin film 21 contg. the Fe 3 C or Fe 5 C 2 or Fe 2 C or the plurality thereof as the essential components of the recording medium. The iron carbide which is intrinsically the material having the low coercive force can, therefore, be imparted with the high coercive force. The magnetic recording medium having all the three conditions that the recording medium is of the thin film type of the continuous film, has the magnetic characteristics equiv. to or better than the magnetic characteristics of the metallic materials and has the chemical stability equiv. to or better than the chemical stability of the iron oxide is obtd. n COPYRIGHT: (C)1990,JPO&Japio |
