Abstract

이 발명은 종래의 자기헤드 코아의 제조에 있어서, 자로의 길이가 길게 형성된 금속 자성막의 낮은 비저항으로 인하여 고주파의 와류 손실에 따른 투자율이 감소하고, 금속 자성막에 의한 자로의 길이가 매우 길어 헤드의 인덕턴스가 증가되기때문에 자기 누설자속에 의한 헤드의 효율을 저하시키는 단점을 해소하기 위하여, 비자성 세라믹 기판에 단차를 형성하고 이 단차영역에 고주파 투자율이 높은 페라이트계 산화물 자성재료와 포화 자속밀도가 높은 금속 자성막이 증착된 페라이트 블럭을 접합시킨 비자성 세라믹 블럭을 적어도 하나 이상 적층시킨 후, 각각 보강홈 및 코일 권선홈이 형성된 비자성세라믹 적층블럭과 홈들이 가공되지 않은 또다른 비자성 세라믹 적층 블럭을 금속 자성막끼리 상호 엇갈리게 접합 형성하여 자기갭층으로 절단 가공함으로써, 포화자속밀도와 투자율이 매우 양호한 복합형 자기헤드 코아를 얻을 수 있는 복합형 자기헤드 코아 및 그 제조방법에 관한 것이다.According to the present invention, in the manufacture of a conventional magnetic head core, the magnetic permeability due to high frequency eddy current loss is reduced due to the low specific resistance of the metal magnetic film having a long magnetic path length, and the magnetic magnetic length of the magnetic magnetic film is very long. In order to solve the disadvantage of lowering the efficiency of the head due to the magnetic leakage magnetic flux due to the increased inductance of the ferrite oxide, the ferrite oxide magnetic material having a high frequency permeability and the saturation magnetic flux density are formed in the nonmagnetic ceramic substrate. After stacking at least one non-magnetic ceramic block bonded to the ferrite block deposited with the high magnetic metal film, the non-magnetic ceramic laminated block formed with the reinforcing groove and the coil winding groove, respectively, and another non-magnetic ceramic laminated block in which the grooves are not processed. Metal magnetic layers are cross-bonded to each other and cut into magnetic gap layers. By, to a saturation magnetic flux density and complex-type magnetic head in the magnetic permeability is very good composite can be obtained the magnetic head core core and a method of manufacturing the same.
