Abstract: A method of manufacturing glass substrates for magnetic disks, in which abrasive particles and metal particles deposited on the surface of a glass substrate in a lapping step are prevented from being carried to a subsequent polishing step to protect the substrate from scratches in the polishing step. A main surface of a glass substrate for a magnetic disk is lapped, the resultant surface is etched to a depth of 0.1 mu m - 3 mu m, and the etched surface is polished.

Abstract: A process is disclosed for reducing the abrasivity of a coated web of material. The web of material runs with its coated side over a deflecting roller (2) and is then treated with an abrasive surface, either along a contact path via guiding or deflecting rollers or along intermediate linear paths in contact with itself. By modifying the relative speeds of both surfaces, the web tension and the length of the contact surface, the abrasion effect may be appropriately adjusted. Rubbed-off particles lying on the surface of the web are sucked off.

Abstract: A magnetic recording medium is formed with a laser textured glass or glass-ceramic substrate. The use of a pulsed, focused laser light beam, such as a CO2 derived laser light beam, enables the formation of an accurately textured landing zone on a glass or glass-ceramic substrate which is substantially replicated on subsequently applied layers.

Abstract: A magnetic disc surface texture (33) utilizes a plurality of structures (44) selectively positioned on the surface of disc (12) for controlling interaction with a slider (16). The plurality of structures (44) have a cross-sectional area that is the same over a selected range so that stiction and friction buildup between the slider (16) and the surface of disc (12) remains relatively constant over repeated contact start-stop operations. Structures (44) reduce a real area of contact between the slider (16) and disc surface to less than one percent of an apparent area of contact between an air bearing surface of slider (16) and disc (12).

Abstract: A magnetic recording medium comprises a non-magnetic substrate (21), a magnetic recording layer (22) formed on the non-magnetic substrate (21), and a lubricant layer (23) containing carbon as a major component and formed on the magnetic recording layer (22). At least one element selected from a group consisting of hydrogen and a halogen is bonded to the carbon, as the major component of the lubricant layer (23), in a surface region of the lubricant layer (23). In the formation of the lubricant layer (23), initially only an inert gas is introduced as an atmospheric gas around a carbon target at the begining of sputtering, so that the carbon target is sputtered by cations of the inert gas. Thereafter, a gas containing at least one of hydrogen and a halogen is added to sputter the carbon target. Thus, a carbon-hydrogen atomic bond (C-H bond) and/or a carbon- halogen atomic bond (C-X bond; X is a halogen element) are formed on the surface region of the lubricant layer (23).
