Abstract

본 발명은 헤드 코일 권선부에 자성막이 트랙폭보다 더 두껍게하여 기록, 재생의 효율을 증대시키는 자기 헤드의 구조 및 그 제조방법에 관한 것으로, 비자성기판에 트랙폭만큼의 자성막 및 절연막이 교대로 성막된 적층자성막이 형성된 것에 있어서, 헤드코일 권선부의 비자성 기판에 홈이 형성되고 이 홈에 자성막이 형성되어 자성막을 비롯한 적층 자성막의 전체 두께가 트랙폭보다 더 두꺼운 구조로 되어지고, 이에 따른 제조에 있어서는, 비자성 기판에 홈기공하고, 이 홈에 자성막을 성막하고 랩핑한후 다시 자성막/절연막을 교대로 성막한후 글라스 성막하고, 이런 공정을 거친 기판을 여러개 적층하여 본딩한후 C-bar에는 권선홈을, I-bar에는 보강홈을 형성하고, 보강홈에 글라스 몰딩하고 갭물질을 성막한후, 상기한 C-bar와 I-bar를 접합하는 공정으로 이루어진 기술에 관한 것이다.The present invention relates to a structure of a magnetic head in which a magnetic film is thicker than a track width in a head coil winding to increase recording and reproducing efficiency, and a method of manufacturing the same. In the multilayer magnetic film formed by using a thin film, a groove is formed in the non-magnetic substrate of the head coil winding portion, and a magnetic film is formed in the groove so that the overall thickness of the laminated magnetic film including the magnetic film is thicker than the track width. In manufacturing according to the present invention, grooves are formed in a non-magnetic substrate, magnetic films are formed and wrapped in the grooves, magnetic films / insulating films are alternately formed, glass is formed, and a plurality of substrates subjected to this process are laminated and bonded. Winding grooves are formed in the C-bar, reinforcement grooves are formed in the I-bar, glass molding is formed in the reinforcement grooves, and the gap material is formed, and then the C-bar and I-bar are joined together. It relates to a technique made.
