Patent ID: 7859799

Claim:
A magnetoresistive head, comprising: a lower magnetic shield layer; a magnetoresistive film including a pinning layer, a first ferromagnetic layer, an intermediate layer, and a second ferromagnetic layer formed on said lower magnetic shield layer; a sensor height direction refill film allocated in the sensor height direction of said magnetoresistive film; and an upper magnetic shield layer formed on said magnetoresistive film and said sensor height direction refill film, said magnetoresistive head applying a sensing current to the interface between said first ferromagnetic layer and said intermediate layer and to the interface between said intermediate layer and said second ferromagnetic layer, characterized in that the length of sensor height direction at bottom surface of said pinning layer is longer than the length of sensor height direction at bottom surface of said first ferromagnetic layer, an angle formed by an edge of said pinning layer in the sensor height direction for the surface extended from bottom surface of said magnetoresistive film is smaller than the angle formed by an edge of said second ferromagnetic layer in the sensor height direction for the surface extended from bottom surface of said magnetoresistive film, and the height of top surface of said sensor height direction refill film is equal to or higher than top surface of said magnetoresistive film.
