摘要

PURPOSE: To set the distance from a magnetic gap on the surface opposite to a recording medium to an inclined side part small by a simple method without reducing the cross-sectional area of a magnetic circuit. ;CONSTITUTION: On a core half 22, the inclined side part 16 inclined at a 1st angle θ to the recording medium surface is formed in a position at a distance A1 from the magnetic gap 12 on the surface opposite to the recording medium, and also a bottom side part 17 continued to this inclined side part and inclined at a 2nd angle smaller than the 1st angle to the recording medium surface is formed. Thus, a small distance can be set between the magnetic gap on the surface opposite to the recording medium and the inclined side part without reducing the cross-sectional area of the magnetic circuit by a simple method.;COPYRIGHT: (C)1996,JPO
