Magnetoresistive sensor with refill film, fabrication process, and magnetic disk storage apparatus mounting magnetoresistive sensor |
摘要 |
Embodiments of the invention provide a high-output magnetic reading head by making it easy to remove a re-deposited substance that deposits on the side wall surface in the track width direction or the side wall surface in the sensor height direction of a magneto-resistance film in a fabrication process of the magnetic reading head. In one embodiment, a refill film that is fabricated first of a refill film along track width direction or a refill film along sensor height direction is fabricated such that a layer in contact with the magneto-resistance film is formed of a material that is slow in etching rate but possible to minimize deterioration of characteristics due to thermal treatment and a layer(s) other than the layer in contact with the magneto-resistance film is formed of a material(s) that is fast in etching rate.
