Abstract:
A thin film magnetic head having an upper magnetic film and a lower magnetic film with a non-magnetic gap film interposed therebetween, wherein an upper end part magnetic film is formed on said upper magnetic film at an end of said upper magnetic film and at one side of said non-magnetic gap film, and a lower end part magnetic film is formed on said lower magnetic film at an end part of said lower magnetic film and at an other side of said non-magnetic gap film, wherein said upper and lower end part magnetic films and said non-magnetic gap film delimit in combination a track width for a magnetic recording medium, and at least one of said upper and lower end part magnetic films is projected more than at least one of said upper and lower magnetic films toward an air bearing surface, and wherein saturable magnetic flux densities of said upper and lower end part magnetic films is higher than saturable magnetic flux densities of said upper and lower magnetic films.
