摘要： Adhesion between a deposited seed layer, e.g., a sputter-deposited NiP seed layer, on an alternate substrate, such as a glass, ceramic or glass-ceramic substrate, is significantly enhanced by depositing a chromium or chromium-alloy adhesion enhancement film between the substrate and seed layer. Magnetic recording media comprising a surface-oxidized NiP seed layer and chromium adhesion enhancement film exhibit low media noise and are suitable for high density longitudinal magnetic recording.

摘要： A glass or glass-ceramic substrate comprising about 0.5 to about 32 wt. % Li.sub.2 O is employed as a non-magnetic substrate of a magnetic recording medium. Migration of Li from the substrate to the medium's surface is prevented by forming an amorphous NiP sealing layer on the substrate, with an optional adhesion enhancement layer therebetween. Embodiments include surface oxidizing the amorphous NiP sealing layer for enhanced recording performance.

摘要： A structure of a film filter includes a plurality of film layers made of a film stack material and a substrate wafer which said film layers are deposited on at a temperature substantially higher than a room temperature and retained to after being cooled to the room temperature. The substrate wafer has a coefficient of thermal expansion greater than that of the film stack material so as to generate compressive forces upon the associated film layers, thus resulting in the film filter having a negative temperature drift coefficient.
