    摘要: A magnetic disc for use in a disc drive data storage system is disclosed. The magnetic disc includes a layer of magnetic material deposited on a substrate and a carbon overcoat layer deposited on the layer of magnetic material. The carbon overcoat layer has a first hardness over a contact start-stop region of the disc. The carbon overcoat layer has a second hardness over a data storage region of the disc. The second hardness is softer than the first hardness and than a hardness of a diamond like coating on an associated magnetic head so that disc asperities in the data storage region of the carbon overcoat layer will wear upon impact with the magnetic head.

    摘要: A magnetic medium has permanently defined boundaries between tracks and a consistent surface smoothness. The crystallographic structure of the magnetic medium is modified at the track boundaries, so the grains of the magnetic thin film permanently take on a relatively non-magnetic structure as compared to the grains of the magnetic thin film within the tracks. Servo patterns on the magnetic medium may be permanently defined at the same time the track boundaries are permanently defined. Laser ablation, laser heating to an amorphous structure, photolithography, perpendicular deposition, ion milling, reverse sputtering, and ion implantation can be used individually or in combination, with either the magnetic layer or the underlayer, to create the relatively non-magnetic areas.

    摘要: A magnetic disc for a computer disc drive has distinct zones of differing lubricant thickness. A bonded+mobile zone covers a portion of the disc which preferably coincides with the landing zone. A zone of different lubricant thickness, such as lubricant-free, bonded-only or mostly-bonded, covers a different portion of the disc such as over the data zone. After a uniform layer of lubricant is coated over the disc surface, lubricant can be removed from distinct zones by solvent removal over a periphery of the disc and by removal by laser. The lubricant removal from distinct zones can occur either before or after bonding. Multiple lubricant thickness zones may be used, and the lubricant thickness profile over the entire disc can be controlled as desired.

    摘要: Magnetic data storage disks, particularly along dedicated transducing head contact regions, are laser textured according to a process in which beam shaping optical components impart an elliptical or otherwise elongated cross-section to the laser beam. Consequently, individual texturing features such as rims and nodules are elliptical or elongate, with more gradual height gradients in directions parallel to their major axes. The texturing features further are oriented with respect to the direction of transducing head accelerations and decelerations, which yields high performance in terms of reduced dynamic friction, reduced stiction and better wear characteristics. Texturing features are formed in a variety of patterns, including patterns with adjacent features contacting one another. A further refinement involves forming features with substantially different slopes on opposites sides of a maximum height region.

    摘要: A tester for use in detecting asperities in a disc surface of a storage system includes a load arm having a proximal end and a distal end. The distal end of the load arm is positioned adjacent the disc surface. A slider is carried on the distal end of the load arm adjacent the disc surface. A thermal sensor is coupled to the slider and provides an electrical output in response to a thermal input due to interaction between the thermal sensor and asperity on the disc surface. Detection circuitry coupled to the thermal sensor detects the electrical output from the thermal sensor and responsively provides a detection output indicating the occurrence of an asperity on the disc surface.
