Patent number: 5644449Abstract: A magnetic head slider assembly for a magnetic recording and reproducing apparatus. A first slide surface and a second slide surface, which are comparatively wide, are formed on the surface of the assembly which will face a recording medium. A first air groove intervenes between the first and second slide surfaces. Part of the first slide surface is formed by a magnetic core. A third slide surface adjoins the first slide surface via a second air groove at the side opposite to the first air groove. The third slide surface is slightly remoter from the medium than the first and second slide surfaces.Type: GrantFiled: April 12, 1996Date of Patent: July 1, 1997Assignee: NEC CorporationInventors: Yuichi Hayakawa, Atsushi Hirano, Yasuhiro Miyata, Koki Takahashi
