Abstract
Method of incorporating atomic oxygen into a magnetic recording layer by sputtering a target containing an oxide of cobalt. The oxide of cobalt may be sputtered to provide a readily dissociable source of oxygen which may increase the concentration of free cobalt atoms (Co) in the magnetic recording layer and also increase oxide content in the magnetic recording layer.
