Abstract: A shallow trench discrete track media structure is fabricated by etching a magnetic recording layer to provide a plurality of discrete magnetic data tracks separated by shallow trenches. Each shallow trench has a trench floor formed at a depth in the magnetic recording layer that is less than the thickness of the magnetic recording layer. Exposed regions of the magnetic recording layer beneath the trench floor are reacted with reactive plasma to diminish the magnetic moment of the exposed regions.

Abstract: The embodiments disclose a method of protecting patterned magnetic materials of a stack, including depositing a thin continuous film of an inert material that is inert to the magnetic materials of a patterned stack upon which the thin continuous film is being deposited and forming a thin interim interface layer from the thin continuous film to protect top and sidewall areas of non-etched higher relief magnetic islands and magnetic film etched surfaces of the patterned stack from air exposure damage and damage from contact with backfilled materials.
