摘要： Thin film disk media which is initially coated with lubricant from the ID or normal head landing area radially outwardly across the data zone. The initially applied lubricant area is thinned and buffed in the data area so as to provide a substantially reduced lubricant layer overlying the data zone characterized by markedly improved coefficient of friction characteristics in relation to what would have been produced without such lubricant removal and buffing.

摘要： A thin film magnetic disc having a carbon overcoat which is characterized by (a) a thickness of less than about 500 .ANG. and (b) surface nitrogen atoms having a nitrogen (1s) electron principle binding energy, as determined by electron spectroscopy for chemical analysis (ESCA), of about 399.4 eV. The nitrogen atoms enhance lubricant adhesion to the overcoat. In a preferred embodiment, the overcoat is formed by sputtering under an argon/hydrocarbon/nitrogen gas atmosphere to produce long resistance-to-erosion times, and high lubricity properties.

摘要： A method for texturing a disc substrate, and a particle slurry for use in the method. The slurry includes two populations of different-size particles, preferably one population containing particles in a 3 micron size range, and a second population containing particles in a 1 micron size range. The particles, when used to abrade the surface of a disc, create a surface texture characterized by a low peak/peak-to-valley ratio.

摘要： A method of evaluating the start/stop lifetime of a thin-film magnetic medium having an overcoat formed by sputtering a carbon-containing overcoat on a magnetic-film substrate. Resistance to erosion of the medium is evaluated by the time required to wear away the overcoat during a high-speed abrasion treatment. Lubricity is measured either in terms of the coefficient of friction of the disc, or in terms or surface hydrophobicity, as gauged by one of a number of measurable surface properties. The method allows for rapid assessment of disc wear properties, and can be used to optimize sputtering conditions required to achieve selected hardness and lubricity properties in a disc overcoat.

摘要： Method and apparatus for treating the surface of a magnetic disc to remove surface asperities and loosely bound material. The disc is alternatively treated by contact with a pair of moving belt-like tapes, a pair of flying heads, and second contact with the belt-like tape, with the disc carried at a fixed position for rotation in a vertical plane throughout, but rotated at a higher speed during the intermediate flying waffling step. The first and/or second tape-treatment steps can be used to apply a lubricant film to the disc surface.

摘要： A discontinuous flash chrome interlayer of about 5 to 25 .ANG. is incorporated between the upper and lower magnetic recording alloy layers. This flash non-magnetic separation layer is so thin that it is, in fact, a discontinuous layer, so that while the benefits of having some chrome flashed on the surface of the first portion of the magnetic recording alloy are achieved, yet the upper and lower magnetic recording alloy layers are not completely physically separated as they are in disks made according to known sputtering processes.
