Abstract
In one embodiment, a magnetic recording medium includes a patterned magnetic recording layer above a substrate, the patterned magnetic recording layer including recording regions and separating regions for separating the recording regions and a non-magnetic alloy layer positioned in the separating regions, wherein the non-magnetic alloy layer includes Ti. In another embodiment, a method for producing a magnetic recording medium includes forming separating regions in a magnetic recording layer by removing portions of the magnetic layer, wherein the separating regions separate recording regions in the magnetic layer, and depositing a non-magnetic alloy layer in the separating regions. Other media and methods are described according to more embodiments.
