Abstract
PURPOSE: To improve recording efficiency of a vertical magnetization type magnetic head by sandwiching a magnetic pole and flank member between nonmagnetic holders and by increasing the number of turns of an energized winding toward the tip part of the flank member.
CONSTITUTION: Magnetic pole 2 is made of a thin magnetic film of high permeability and on its flank, flank member 3 made of Mn-Zn ferrite, etc., is formed in close contact. Magnetic pole 2 is sandwiched between the 1st nomagnetic holder 5 having flank member 3 buried and the 2nd nonmagnetic holder 6. Nonmagnetic holders 5 and 6 are provided with winding holes 5a and 6a having notches deep in the tip part direction of flank member 3 and wound with winding 4 so that the member of turns will increase toward the tip part of flank member 3.
