Abstract

PURPOSE:To obtain a high-quality and uniform magnetic field distribution with a comparatively simple constitution and high workability, by changing previously an energizing coil into a pattern around the upper part of a side face member and then joining a magnetic pole to the side face member. CONSTITUTION:A magnetic pole block 11 is formed with nonmagnetic holders 15a and 15b which are arranged with their tip parts opposite to the recording face of a magnetic recording medium and hold magnetic poles 14 and 11 at both side of them. For an energizing coil block 12, a square through-hole 18 for insertion of the side face member is formed to a nonmagnetic substrate 17 and a square energizing coil 19 is provided around the hole 18. A side face member block 13 is formed by joining nonmagnetic holders 22a and 22b to both sides of a side face member 21 made of a high permeability magnetic material. A projected part 23 is formed at the upper edge part of the member 21 and inserted into the hole 18. The upper face of the part 23 is joined close to the lower face of the pole 14 into a magnetic body.
