Abstract

본 발명은 정보 기록 재생용 자기저항 헤드(Magnetoresistive Head)에 관한 것으로, 좀더 구체적으로는 자기 저항 소자(3)와 바이어스를 위한 바버풀(2)로 구성된 자기저항 헤드에 있어서, 자기저항 소자에 전류에 의한 자기계를 인가하는 바이어스 도전체(4)를 형성하고 바버폴(2)과 자기저항 소자(3)의 길이방향이 이루는 각를 46~65°로 하여 제조한 자기정항 헤드에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetoresistive head for information recording and reproducing, and more particularly to a magnetoresistive head composed of a magnetoresistive element 3 and a barbpool 2 for bias. Forming a bias conductor 4 for applying a magnetic field by It is related with the self-regulating head manufactured by making 46-65 degrees.

본 발명에 의해 자기저항 헤드를 제조한 결과 전류의 흐름과 자기 저항 소자의 자화사이의 각도가 45°로 유지되는 부분이 증가하였으며 바이어스 도전체(4)에 의한 자계가 존재함에 따라 바버풀(2)과 자기저항 소자(3)의 길이방향 사이의 가도를 증가시킬수 있고, 자기저항 소자내에 바버풀이 차지하는 면적을 감소시킬 수 있었으며, 기존의 바버풀 바이어스 방식의 자기저항 헤드보다 출력전압과 선형성이 향상된 자기저항 헤드를 얻을 수 있었다.As a result of manufacturing the magnetoresistive head according to the present invention, the portion where the angle between the flow of current and the magnetization of the magnetoresistive element is maintained at 45 ° has been increased, and as the magnetic field caused by the bias conductor 4 is present, ) Between the longitudinal direction of the magnetoresistive element 3 In addition, the area of the magnetoresistive element in the magnetoresistive element can be reduced, and the magnetoresistive head with improved output voltage and linearity can be obtained.

따라서 본 발명의 자기저항 헤드는 기존의 바버풀 바이어스 방식을 이용한 자기헤드보다 높은 효율을 가지게 되어, 고밀도 기록장치의 재생헤드로 적용할 수 있다.Therefore, the magnetoresistive head of the present invention has higher efficiency than the magnetic head using the conventional bubble pull bias method, and can be applied as a reproduction head of a high density recording apparatus.
