Abstract

본 발명은 복합 자기 헤드에서 백 갭(Back gap)의 면적을 크게 함으로서 백 갭의 자기저항을 줄여 헤드의 효율을 증대시키기 위한 것으로, C-코어와 I-코어에 권선홈과 트랙홈이 가공된 대향면에 금속자성막이 성막되고 Glass로 접합된 자기헤드에 있어서, 헤드 폭(Cw)에 2개의 트랙홈(8)을 형성하여 백 갭(Back gap)(7)면적을 크게 함과 함께 갭연장부(10)가 형성되고 접동면 계단층(9)을 갖게 함을 특징으로 하는 복합 자기 헤드 구조에 관한 기술임.The present invention is to increase the efficiency of the head by reducing the magnetoresistance of the back gap by increasing the area of the back gap in the composite magnetic head, winding and track grooves are processed in the C-core and I-core In a magnetic head in which a metal magnetic film is formed on an opposite surface and bonded to glass, two track grooves 8 are formed in the head width Cw to increase the back gap area and increase the gap. A technique for a composite magnetic head structure, characterized in that the section (10) is formed and has a sliding surface step layer (9).

Claims (2)

C-코어 및 I-코어에 권선홈과 트랙홈이 가공된 대향면에 금속자성막이 성막되고 글라스(Glass)로 접합된 자기 헤드에 있어서, 헤드 폭에 2개의 트랙홈(8)을 형성하고 이 트랙홈 접동 바깥면(C2)에는 일정 깊이로 절단된 접동면 계단층(9)을 형성하며 상기 접동 바깥면(C2) 사이에는 접동면(C1)을 형성하여서 됨을 특징으로 하는 복합자기 헤드.In a magnetic head in which a magnetic metal film is formed on the opposite surface where the winding grooves and the track grooves are processed on the C-core and the I-core and glass-bonded, two track grooves 8 are formed in the head width. The track groove sliding outer surface (C 2 ) forms a sliding surface stepped layer 9 cut to a predetermined depth, and the sliding magnetic surface (C 1 ) is formed between the sliding outer surface (C 2 ) head. 제 1 항에 있어서, 접동면 계단층(9)의 가공깊이(H)를 갭깊이(d)보다 크게 함을 특징으로 하는 복합자기 헤드.2. The composite magnetic head as claimed in claim 1, wherein the processing depth (H) of the sliding surface step layer (9) is made larger than the gap depth (d). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
