Abstract

PURPOSE:To improve the reproduced output characteristic of isolated waves and frequency characteristics by incorporating hexagonal planar ferrite magnetic powder having >=10 average planar ratio and specified acicular magnetic powder at specified ratios into a titled medium. CONSTITUTION:The hexagonal planar ferrite magnetic powder having >=10 average planar ratio and the acicular magnetic powder which has the coercive force corresponding to the 95-125% range of the coercive force of the planar ferrite magnetic powder, >=100emu/g powder saturation magnetization and >=3 average acicular ratio are incorporated in a 60:40-95:5 range into this medium. Fine acicular powder of iron alloys or iron nitride, etc., is usable as the acicular magnetic material to be used in conjunction with the planar ferrite magnetic powder. The coating type magnetic medium having the large reproduced output of the isolated waves and the excellent recording density characteristic is thereby obtd.
