MAGNETIC STORAGE MEDIA HAVING TILTED MAGNETIC ANISOTROPY

摘要

A magnetic storage media (18, 38) comprises a substrate (20, 40) supporting the layer of magnetic media ( 28, 48) having a tilted C-axis greater than approximately 25° with respect to surface normal and having a magnetic easy axis tilted at an angle at approximately greater than 30° from the substrate surface normal. The media includes an oblique deposited seedlayer structure (22, 42) directing tilted C-axis growth of the magnetic material layer independent of the angle of deposition of the magnetic material layer. The orientation C-axis and the magnetic easy axis of the media may be organized into circumferential or radial patterns on the substrate surface, and additionally may possess azimuthal symmetry.
