Description

자기 헤드Magnetic head

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명을 설명하기 위한 자성막의 경사각도와 보자력과의 관계를 도시한 특성도.3 is a characteristic diagram showing the relationship between the tilt angle and the coercive force of the magnetic film for explaining the present invention.

제4도는 본 발명의 1 실시예를 도시한 자기 헤드의 주자로 형성면 평면도.4 is a plan view of a surface formed by a runner of a magnetic head showing one embodiment of the present invention;

제5도는 본 발명의 다른 실시예를 도시한 자기 헤드의 주자로 형성면의 평면도.5 is a plan view of a surface formed by the runners of the magnetic head, showing another embodiment of the present invention.

Claims (6)

자기 갭을 거쳐서 2개의 코어 반체대가 접합되어 되는, 자기헤드에 있어서, 상기 코어 반체의 보호재의 적어도 한쪽에 코일 권선용 홈을 가지며, 그 코일 권선용 홈의 내벽에 형성된 자성막으로 자기회로를 구성하여 되며, 그 코일 권선용 홈의 자기 갭측과 반자기 갭측의 측벽과 갭면과의 이루는 각도를 각각 20도 이상 80도 이하의 범위로 하는 것을 특징으로 하는 자기 헤드.In a magnetic head in which two core half bands are joined via a magnetic gap, at least one of the protective members of the core half has a coil winding groove, and a magnetic circuit is formed by a magnetic film formed on the inner wall of the coil winding groove. And an angle formed between the magnetic gap side of the coil winding groove, the side wall on the semi-magnetic gap side, and the gap surface is in a range of 20 degrees or more and 80 degrees or less, respectively. θ1과 θ2을 30도 이상 60도 이하로 하는 것을 특징으로 하는 특허청구의 범위 제1항 기재의 자기 헤드.The magnetic head according to claim 1 , wherein θ 1 and θ 2 are 30 degrees or more and 60 degrees or less. 상기 코일 권선 홈 낮은 부의 각이 곡율을 갖게하는 것을 특징으로 하는 특허청구의 범위 제1항 또는 제2항 기재의 자기 헤드.The magnetic head according to claim 1 or 2, wherein the angle of the lower portion of the coil winding groove has a curvature. 2개의 코어반체를 구성하는 보호재가 비자성재 혹은 낮은 투자율의 페라이트인 것을 특징으로 하는 특허청구의 범위 제1항 기재의 자기헤드.The magnetic head according to claim 1, wherein the protective material constituting the two core bodies is a nonmagnetic material or a ferrite of low permeability. 적어도 한쪽의 보호재의 코일 권선창 반대쪽에 절결홈을 마련한 것을 특징으로 하는 특허청구의 범위 제1항의 기재의 자기 헤드.A magnetic head as set forth in claim 1, wherein a cutout groove is provided on the opposite side of the coil winding window of at least one protective material. 기록매체 대향면에서 보아, 트랙쪽이 코어 폭 보다 좁게 조여져 있고, 그 조인부 경사면의 적어도 한 쪽에 자성막이 형성되어 있으며, 자성막의 측부가 자기 갭과 평행부를 갖지 않도록 한 것을 특징으로 하는 특허청구의 범위 제1항 기재의 자기 헤드.From the opposite side of the recording medium, the track side is tightened narrower than the core width, a magnetic film is formed on at least one side of the inclined surface of the joining portion, and the side of the magnetic film has no side portion parallel to the magnetic gap. Scope of the magnetic head of claim 1. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
