Abstract

Apparatus for recording data and method for making the same. In accordance with some embodiments, a recording layer is supported by a substrate. The recording layer has a granular magnetic recording layer with a first oxide content, a continuous magnetic recording layer with nominally no oxide content, and an oxide gradient layer disposed between the respective granular magnetic recording layer and the continuous magnetic recording layer. The oxide gradient layer has a second oxide content less than the first oxide content of the granular layer.
