The Invention Provides a Positioning System for a Linear Data Storage Medium, Such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of multiple actuators to control the positioning of sliders carrying read and write elements, e. g. , separate sliders carrying the read and write elements, relative to the data storage medium with multiple degrees of freedom. The multiple degrees of freedom may include two or more of a vertical position, a horizontal position, a transverse position, an azimuth position, a zenith position, and a yaw position. In this manner, the invention can improve head-to-track alignment of read heads and write heads with linear data storage systems having very small track pitches, such as track pitches approximately 1 micron and especially less than 1 micron.

A sputtered metal film recording medium includes a substrate, a texture promotion layer sputtered on a first side of the substrate, a seed layer deposited on the texture promotion layer, an intermediate layer including a chromium alloy deposited on the seed layer, and a longitudinal magnetic recording layer including a cobalt alloy deposited on the intermediate layer. The texture promotion layer configures in-plane orientation of a cobalt structure in the magnetic recording layer.

A dual-input, automatic-switching power supply comprises a primary power input, a secondary power input, and a power output. Included are first and second DPST mechanical relays and a third DPDT mechanical relay. A first relay input is connected to the primary power input and a corresponding first relay output is connected to a third relay input. A second relay input is connected to the secondary power input and a corresponding second relay output is connected to a different third relay input. The third relay output is connected to the power output. The relays in combination provide a relay moving contact gap spacing, source to source, of at least three millimeters. A first under voltage control module maintains the first and third relays in states causing the primary power input to be connected to the power output as long as voltage from the primary power input remains above a preestablished primary voltage dropout level. A second under voltage control module maintains the second relay in a state causing the secondary power input to be connected to the second input pin of the third relay as long as voltage from the secondary power input remains above a preestablished secondary voltage dropout level. A flip-flop is used to automatically switch the third relay to a state causing the primary power input to be disconnected from, and the secondary power input to be connected to the power output when the primary power input voltage drops below the primary voltage dropout level.

A metallic, thin film, magnetic recording medium is disclosed wherein the surface of the metallic thin film is modified such as to promote improved adhesion with protective lubricant. A process is disclosed wherein, for example, controlled oxidation of a metallic, thin film magnetic recording medium yields a homogeneous distribution of bonding sites and wherein application of a protective lubricant (e. g. , perfluoropolyether compositions) provides a recording medium exhibiting superior wear and abrasion resistance.

A method of mixing ferromagnetic recording media comprising the steps of: (i) coating a non-magnetic substrate material with a magnetic layer comprising Co-Cr by sputtering; (ii) after sufficient thickness built-up, introducing a gas (hydrocarbon, N. sub. 2, NH. sub. 3, or O. sub. 2) into sputtering process to deposit a layer of Co and Cr reaction products under the following conditions: (a) film growth at least 50 Angstroms per minute; and (b) fully reacting Co and Cr wtih gas introduced; (iii) coating reactively sputtered layer with lubricant. Reactively sputtered layer promotes improved adhesion of lubricant to recording media.
