Abstract
PURPOSE: To prevent the leakage between winding and core and enable the formation of the edge part thereof to be performed without decreasing mass productivity in the production process of the magnetic head by constituting the edge portion of the magnetic head with glass.
CONSTITUTION: Head core 11 is of core width W and its effective track width is W'. The effective track width W' is determined by the depth of the notch part 12 molded by glass. The width L of the notch part 12 is made wider than the width L' of a winding window 13. Glass 16 is also deposited on the winding groove 15 of the winding, if necessary. If the winding is applied to the core constituted in this way, the portion where the winding 17 makes edge contact with the head core 11 is constituted by the glass 18 and therefore even if the insulation covering of the winding 17 receives damaging at this edge portion, the occurrence of leakage between the winding 17 and core 11 is obviated.
