摘要： Generally, methods and apparatus are disclosed for fabrication of angle-of-incidence layers on a substrate. In one embodiment, the angle-of-incidence layers may have either radial or circumferential tilt symmetry, using, for example, sputtering or evaporation techniques. In one example, an apparatus for sputtering material comprises a substrate support member, a cathode positioned in substantially facing relationship with respect to the substrate support member and a shutter plate. The shutter plate is disposed between the substrate support member and the cathode and defining an aperture for selective transmission of sputtered articles from the cathode on the basis of a non-perpendicular trajectory angle relative to a plane of the substrate support member.

摘要： A thin film structure in the form of, for example, a magnetic recording medium having a deceased C-axis distribution is provided. The structure includes a substrate having a first surface and a second surface non-parallel to the first surface, a seed layer overlying the first surface and the second surface of the substrate and a magnetic material layer on the seed layer. The magnetic material layer has a C-axis tilted with respect to an axis perpendicular to the magnetic material layer, i.e., a surface normal of the magnetic material layer. The seed layer has a columnar structure oriented generally perpendicular to either the first surface or the second surface of the substrate. The columnar structure of the seed layer acts as a template to epitaxial growth.
