抄録

Two kinds of acicular cobalt ferrite fine particles which differed in size (long axis : about 1.2μm and 0.4μm) were prepared by conventional sintering method. Then two kinds of acicular cobalt ferrite tapes were fabricated with these fine particles and binder regins. The recording characteristics of these tapes were measured by using commercially available open reel tape deck. The output of the magnetic tape made of acicular particles, of the order of 1.2μm decreased linearly in the high density recording region because of a spacing loss. The output of the magnetic tape made of the acicular particles, of the order of 0.4μm increased in the high density recording region.<BR>This was because the fine particles were densely packed in the medium and the roughness of the surface of the tape was smoothed by improving the dispersive quality.
