IPC: C09D7/12
Filed: 1994-08-04
Abstract: PURPOSE: To magnetize a thick magnetic layer by a magnetic head by arraying magnetic fine particles so that the magnetic head has a numeric gradient of the magnetic field strength and indicates a specific value. CONSTITUTION: A numeric gradient of a magnetic field strength H of a head is expressed by formula I, and magnetic fine particles are arrayed so that the magnetic field indicates a maximal magnetic field strength or a strength value close to it at least at each write position on a magnetic recording carrier with respect to a stationarily standardized distance z/g between a head mirror face and an upper face of the magnetic recording carrier. The magnetic fine particles in a magnetic layer are arrayed so that an easy axis forms an inclined angle of 6 to the running direction X of the carrier. The carrier runs in the running direction X=A, while in (b) it runs in the inverse direction X=B, and this brings a vertical gap z to the magnetic head with a head air gap length (g). Thus, a thick magnetic layer can be magnetized by the magnetic head.
