摘要： 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.

摘要： A lower core is formed on the surface of a wafer and then a protection film made of substance that has a lower ion milling rate than that of the lower core is formed so as to coat the lower core. Then, the protection film is ground to expose the lower core under the film, and the surface of the protection film and that of the lower core are finished smooth and level. Then, ion beams are radiated to simultaneously mill both the protection film and the lower core and thereby form a recess above the lower core. Next, a gap layer is formed on the surfaces of both the protection film and the lower core. Then, an upper core is formed in the recess above the lower core with a gap layer between them. Accordingly, only the part in which the pole of the upper core and the pole of the lower core face each other in parallel is magnetically effective. This ensures a constant track width even in mass production provided that only the lower core is formed strictly in accordance with the design. In this case, formation of a lower core in accordance with the design is possible. Further, since the surplus part of the upper core does not actually provide a read/write function of a head, cross-talk is seldom generated between adjacent tracks. Conducting milling before forming an upper core elminates magnetic shortcircuiting between the upper and lower cores.

摘要翻译： 在晶片的表面上形成下芯，然后形成具有比下芯的离子研磨速度低的物质制成的保护膜，以涂覆下芯。 然后，保护膜被研磨以暴露膜下的下芯，保护膜的表面和下芯的表面光滑平整。 然后，照射离子束同时研磨保护膜和下芯，从而在下芯上形成凹陷。 接下来，在保护膜和下芯的表面上形成间隙层。 然后，在下部芯部上方的凹部中形成上部芯部，在它们之间具有间隙层。 因此，只有上芯的极和下芯的磁极平行的部分才是磁性有效的。 即使在大规模生产中也能确保轨道宽度恒定，只要根据设计严格地形成下芯。 在这种情况下，可以根据设计形成下芯。 此外，由于上层的剩余部分实际上不提供头的读/写功能，所以在相邻轨道之间很少产生串扰。 在形成上芯之前的导电铣削可以使上，下芯之间的磁短路导致电磁场短路。

摘要： A method of manufacturing an air flow type thin film magnetic head includes the steps of providing a slider for a thin film magnetic head; forming a photo-sensitive layer directly on the slider; subjecting the photo-sensitive layer to a light beam having controlled loci to form a desired pattern on the photo-sensitive layer, the loci of the light beam corresponding to the configuration of rails to be formed on a surface of the slider; and forming the rails in accordance with the desired pattern. The loci of the light beam is controlled by a data processor. Various rail patterns including an asymmetrical and non-parallel rail pattern can easily be formed on a slider of a magnetic head.

摘要： 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.

摘要： 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.

摘要： 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.
