Abstract: A thin film magnetic head made of material having the magneto-resistance (MR) effect and its manufacturing method are provided. A lower shield layer for magnetically shielding an MR film is formed with a trench of a gull-wing shape having a flat bottom surface and opposite slanted surfaces formed on both sides of the bottom surface. The MR film is formed on the lower shield layer conformal to the gull-wing shape. The region of the MR film on the flat bottom surface forms an effective magnetic active region. A track center shift and the generation of a side-lobe in the off-track characteristic specific to an MR head can be suppressed and high density recording and reproducing of narrow tracks are possible.

Abstract: On a lower magnetic shield film, a lower gap film is formed on which a conductive lead film and a magnet film is laminated. The magnet film forms a bias permanent magnet film for generating a single magnetic domain of a magneto-resistance film. This lead film is trenched to the lower gap layer (20) to form a trapezoid trench and separated leads. A sensor unit having the magneto-resistance film is formed conformally to the trench and electrically connected to the separated leads. An upper gap is formed on the sensor unit (28), and an upper shield is formed on the upper gap.

Abstract: A lower pole gradually increases its thickness in a section from the pole front end surface toward the depth direction.

Abstract: In an induction- and MR-type composite magnetic head of the type that one of two shield films of an MR-type magnetic head serves as one of two cores of an induction-type magnetic head, conductive leads are thicker than an MR element so that steps are formed at the boundaries between an MR element sensitive region and the conductive leads. An upper gap layer has a constant thickness and has a recess 56 on its upper surface because of topographical transfer of the underlying steps. An upper shield--lower core layer has a downward convex at its lower surface, because of topographical transfer of the recess on the upper surface of the upper gap layer. However, the upper surface of the upper shield--lower core layer is flat and parallel to the MR element. Therefore, a write gap layer formed thereon is made flat and parallel to the MR element. Steps of the write gap can be removed and a record density can be increased.

Abstract: After both an ABS and a back surface of a slider are lapped, a one-surface lapping resulting in balanced compressive stresses of the ABS is performed resulting in unbalanced stresses to make the ABS flat while warping the ABS. At this stage, the slider deforms by changing the back surface in a convex shape, and the ABS itself is maintained flat by the lapping. Thereafter, a one-surface lapping of the back surface is performed to reduce the compressive stresses therein and make the back surface flat while warping the back surface. The slider deforms by changing the ABS in a convex shape and a positive crown on the ABS is formed. The ABS can be lapped flat, and in addition the crown can be formed. Reliability of data read/write can be improved.
