Claims (3)

  1. 자기 회로가 공기 베어링 면을 갖는 제1자기 코어 및, 접착제에 의해 제1자기 코어의 종측 중심측과 보유부재의 중심측이 서로 일치하도록 로드 아암용으로 제공된 외팔보 보유 구조체의 보유 부재에 연결된 제1자기 코어의 배면 및 자기 갭을 통해 와이어가 감겨지는 제1자기 코어와 완전히 연결되는, 제2자기 코어에 의해 구성되도록 배열된 모노리스형 부유 자기 헤드에 있어서, 상기 자기 헤드는, 자기 헤드의 제1자기 코어 배면상에 설치되고 자기 갭 라인에 대체로 평행하게 설치되며 보유 부재와 맞대고 있으며 또한 상기 자기 갭 라인에 인접한 엣지라인 및 자기 갭 라인 사이의 거리가 제1 및 제2자기 코어 전체 길이의 2내지 20퍼센트인, 홈을 포함하는 것을 특징으로 하는 부유 자기 헤드.
  2. 제1항에 있어서, 상기 홈의 개구부 쪽은 0.1 내지 1㎛이고, 깊이는 0.01 내지 0.3㎛인 것을 특징으로 하는 부유 자기 헤드.
  3. 제1항에 있어서, 상기 보유 부재 및 제1자기 코어를 서로 연결시키기 위한 접착제는 상기 홈 안으로 유입되며 또한 어떠한 접착제도 제2자기 코어에 부착되지 않는 것을 특징으로 하는 부유 자기 헤드.
    ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
