Abstract: A method in accordance with our invention for providing texture bumps on a substrate comprises the step of forming elliptical ridge-shaped bumps on the substrate. In one embodiment, substrate is used in the manufacture of a magnetic disk used in a disk drive. The elliptical bumps cause less vibration of the read-write head than circular bumps. The elliptical bumps also provide reduced friction between the disk and a read-write head during use.

Abstract: A method for preparing a magnetic recording medium comprising the steps of: dispersing ferromagnetic particles in a binder solution; coating the resulting magnetic coating composition on a nonmagnetic support to provide a magnetic layer; drying the magnetic layer; and providing a calendering treatment with the magnetic layer, wherein the binder solution comprises at least one compound selected from the group consisting of a polyurethane resin having a tan .delta. peak temperature of 30.degree. C. or higher as a result of measuring dynamic viscoelasticity, a cellulose acetate butyrate, a cellulose acetate propionate, and a butyral resin; and when the magnetic layer is dried until the solvent content of the magnetic layer is in the range of from 0.1 to 3 wt %, the calendering treatment is provided with the magnetic layer.
