摘要： PROBLEM TO BE SOLVED: To prevent the height of floating from being decreased due to the decrease in the atmospheric pressure at highlands, after the floating profile on the ground level is made approximately uniform, and to make the decrease in the height of floating approximately constant over the whole surface of a magnetic disk, in a magnetic head slider equipped with an air inflow edge and an air outflow edge.
SOLUTION: The slider or the magnetic disk having the slider is provided with a front step bearing formed on the side of the inflow edge, a rail surface formed between the front step bearing and the outflow edge, and a first and a second side pads disposed facing each other with respect to the width direction of the slider and formed between the rail surface and the outflow edge, in which the length of the first or the second side pad with respect to the width direction of the slider is longer than the length with respective to the length direction of the slider.

摘要： PROBLEM TO BE SOLVED: To improve reliability of a magnetic head having a sacrifice anode provided for preventing corrosion of a recording element or a reproduction element during a manufacturing process of a magnetic head. SOLUTION: The sacrifice anode 115 is arranged such that it is exposed on a surface opposite to a surfacing plane of a slider or a plane adjacent to the surfacing plane. After a wet process in which a highly corrosive liquid or water is used has been completed, a surface of the sacrifice anode 115 is covered by a protective film or the sacrifice anode itself is removed.

摘要： PROBLEM TO BE SOLVED: To process the height of an MR element with an accuracy of ±0.020 μm or less in order to improve an output characteristic of the magneto-resistance effect element (MR element) of a magnetic head slider.
SOLUTION: A combination of a plurality of upper and lower shafts 27 which are perpendicularly displaced by two flat springs and a plurality of load adding mechanisms 19 for loading the upper and lower shafts 27 individually with a polishing load via an adaptor 20 is fixedly arranged on a head polishing positioning mechanism 16 at a predetermined pitch, and each bottom end part of the upper and lower shafts 27 is made to hold the magnetic head slider 1 individually via an adhesive elastic body 29 to pressurize a polishing batholith 15, and the polishing load is individually controlled while detecting a resistance value of the MR element of each magnetic head slider 1 by a resistance detecting circuit substrate 31 in process of being polished. Thus, it becomes possible to attain an accuracy of ±0.010 μm or less for the height of the MR element, and a reproduction output of the MR element is stabilized, and also a yield of an MR manufacturing process can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a thin film magnetic head slider small in the working level difference of a floating surface and reduced in its variation, and to provide its manufacturing method.
SOLUTION: The thin film magnetic head slider has a slider substrate 1 consisting of sintered ceramics of Al
2 O
3 -TiC or the like, an underlying insulator film 2 consisting of Al
2 O
3 formed by sputtering on the substrate or the like, a magneto-resistance effect type head 3 being a reproducing head, which is stacked on the film 2, a separation insulator film 4, an inductive recording head 5 and a protective film 6. Moreover, the slider has a floating surface protective film 7 on the floating surface and a second floating surface protective film 8 is formed between the floating surface protective film 7 and the slide substrate 1. Since the slider substrate 1 being the hardest in the touch lap of the floating surface disappears from subjects for sharpening by forming the second floating surface protective film 8, the working level difference of the floating surface can be reduced.
