| 20090195931 | HEAD SLIDER AND METHOD OF MANUFACTURING HEAD SUSPENSION ASSEMBLY - A method of manufacturing a head suspension assembly for mounting a head slider on a suspension includes an irradiating light step, acquiring position information step and head slider mounting step. The irradiating light step is the step of irradiating light on a protective film and a marker at an incidence angle θ. The acquiring position information step is the step of acquiring position information of the marker by measuring reflected light from the protective film and that of the marker. The head slider mounting step is the step of mounting the head slider at a predetermined position of the suspension by using the difference of the intensity of reflected light from the protective film and that of the marker. | 08-06-2009 |
| 20100020444 | HEAD SLIDER IN MAGNETIC DISK DRIVE - A head slider in a magnetic disk drive wherein provisions are made to facilitate the evaporation of lubricant adhering to the slider and thereby substantially reduce the chance of the fly height of the slider becoming unstable due to a lubricant drop. A head element, a heat generating element, and a multilayered heat conducting structure formed from multiple layers stacked along a longitudinal direction of the slider, with at least one layer extending up to portions near both lateral sides of the slider, are embedded into a nonmagnetic insulating layer formed in an air exit end portion of the slider. The heat generated by the heat generating element is efficiently conducted throughout the nonmagnetic insulating layer to heat the entire structure of the nonmagnetic insulating layer. As a result, the lubricant adhering to any portion of the nonmagnetic insulating layer is efficiently heated, causing the lubricant to evaporate or flow. | 01-28-2010 |
| 20100302683 | Magnetic head slider having ultra thin base layer with group 6aelement and protective layer - A magnetic head slider according to the present invention comprises: a slider body including either a write head element or a read head element or both the write head element and the read head element; a seed layer provided on an air bearing surface of the slider body, the seed layer covering either the write head element or the read head element or both the write head element and the read head element, the seed layer having a film thickness that is less than 1 nm; and a protective film formed of diamond-like carbon, the protective film covering the seed layer. The seed layer is mainly formed of silicon and contains a 6A group element in a proportion of 2 atomic fractions or more and 30 atomic fractions or less. | 12-02-2010 |
| 20100315743 | MAGNETIC READ/WRITE HEAD SUBSTRATE - A substrate for a magnetic read/write head is disclosed. The substrate can reduce detachment of crystal grains when unexpected vibrations or impacts are applied. The substrate may be machined when the substrate is cut into strips or a flow path surface recess is formed to produce the magnetic read/write head. The reduced detachment of crystal grains makes the magnetic read/write head more resilient to chipping, which allows the magnetic read/write head to have good performance in read/write. | 12-16-2010 |
| 20100321830 | SLIDER BODY WITH SELECTIVE HARD COMPONENT REMOVAL - A slider is formed of a two-phase material having a first component and a second component that is harder than the first component. A media-facing surface is formed on two-phase material, with a leading edge extending transversely from the media-facing surface. The second component is selectively removed from the two-phase material in a contact region located along at least one of the leading edge and the media-facing surface, such that a hardness of the slider is reduced in the contact region. | 12-23-2010 |
| 20110058279 | OVERCOAT HAVING A LOW SILICON/CARBON RATIO - A slider for an information storage system. The slider comprising a single overcoat layer, wherein the layer is deposited onto an ABS of the slider by a filtered cathodic arc process, the layer having a Si/C ratio less than about 10% and a thickness of less than about 15 Å. | 03-10-2011 |
| 20110116192 | HEAD-SLIDER INCLUDING THIN-FILM MAGNETIC-RECORDING HEAD HAVING REDUCED THERMAL PROTRUSION - A head-slider. The head-slider includes a slider, and a thin-film magnetic-recording head. The thin-film magnetic-recording head includes: a read element; a write element; a non-magnetic insulating protective layer disposed around both read and write elements; a resist disposed at a position further away from an air-bearing surface than the read element; and, a hard-material member including a material selected from the group consisting of silicon carbide and tungsten, which is disposed at a position further away from the air-bearing surface than the read element and the write element. Both an end of the resist and an end of the hard-material member overlap the write element when viewed in a stacking direction. A ratio of a distance from the air-bearing surface to a deepest end of the hard-material member to a distance from the air-bearing surface to a deepest end of the resist is at least 0.9. | 05-19-2011 |
| 20140153136 | NOVEL FILL-IN CONTACT LAYER FOR SLIDER AIR BEARING SURFACE PROTECTIVE COATING - A magnetic slider for magnetic data recording constructed by a process that allows for careful control of seed layer and overcoat thickness. The slider is treated by a process that result in surface pits and scratches. A refill layer is used to fill in the pits and scratches, the refill layer being constructed of a material that does not include Si or carbon. An angled ion beam etching can be used to remove portions of the refill layer that extend outside of the pits and scratches. Then, a seed layer comprising Si and a protective layer comprising C are deposited over the surface. Because the refill layer does not contain either of Si or C, the thickness of the seed layer and carbon overcoat can be accurately measured and controlled, without the refill layer being mistaken for seed or overcoat material. | 06-05-2014 |

The slider has a pattern, which can be a micro-pattern, of SAM material on the air-bearing surface (ABS). The pattern comprises discrete unconnected features, such as dots or lines, that may or may no cover the entire ABS. Methods of micro-printing on the ABS are also provided. | 05-26-2016 |
