摘要： According to embodiments of the present invention, a magnetic head slider provided with a heater disposed near a read element to adjust flying height, is required to increase a thermal protrusion by heat generated by the heater without increasing a thermal protrusion attributable to heat generated by a recording current or environmental temperature. A magnetic head slider includes a thin-film head unit including a read element, a heater having a thin heating line extended above and below the read element, a write element, and an insulating layer of alumina (Al2O3) or the like insulating those components. The thin heating line of the heater is formed from a thin resistive film of NiCr or the like. The thin heating line of the heater is extended above and below the read element so as to meander in a zigzag shape in a direction perpendicular to the device forming surface. The thin heating line has a thickness between about 0.1 and 0.2 μm, a width between about 1 and 3 μm, a length of about 100 μm, and a resistance between about 50 and 500 Ω.

摘要： Embodiments in accordance with the present invention provide a thin-film head formed on an AlTiC substrate of a magnetic head slider. A thin-film head include a write element, a read element, a heater, an alumina insulating film that separates the elements and heater from one another, electric wiring films leading to the respective elements, and an alumina protective insulating film that protects all the layered films. For this configuration, in order to maximize a change in a flying height caused by heat dissipated from the heater and minimize a change in the flying height caused by heat dissipation derived from a recording current, the write element is first formed on the AlTiC substrate and the read element is formed on the write element. An adiabatic layer made of a material exhibiting low thermal conductivity may be formed between the write element and the read element and heater.

摘要： Various embodiments of the present invention pertain to enabling location specific burnishing of a disk. According to one embodiment, the smoothness of a disk is evaluated by gliding over a disk to determine if there is an asperity on the disk. If there is an asperity on the disk, a location of the asperity is stored to enable location specific burnishing of the disk.
