PROBLEM TO BE SOLVED : To manufacture a magnetic probe having a high spatial resolving power of about 20 nm to manufacture a magnetic recording medium having a recording density higher than conventional recording density.
SOLUTION : The compositional ratio of a rare earth metal and a 3d transition metal, both of which constitute a magnetic alloy (especially an amorphous alloy material), is set so as to be received in a compensation compositional ratio or the compositional ratio in the vicinal region of the compensation compositional ratio when a magnetic body comprising the magnetic alloy is provided at the leading end part of the magnetic probe. |
