发明名称 Systems and methods for forming magnetic recording media with improved grain columnar growth for energy assisted magnetic recording
摘要 Systems and methods for forming magnetic recording media with improved columnar growth for energy assisted magnetic recording are provided. In one such method, a first sub-layer of a magnetic layer is formed on a substrate, the magnetic layer including a magnetic material and a plurality of non-magnetic segregants, a top surface of the first sub-layer is etched to substantially remove the non-magnetic segregants accumulated on the top surface, and a second sub-layer of the magnetic layer is formed on the first sub-layer.

主权项 1. A method for fabricating a magnetic recording medium to increase a thickness of a magnetic recording layer of the magnetic recording medium, the method comprising: forming a first sub-layer of the magnetic recording layer on a substrate, the magnetic recording layer comprising a magnetic material and a plurality of non-magnetic segregants, wherein the forming the first sub-layer of the magnetic recording layer causes the non-magnetic segregants to accumulate over the magnetic material and at a top surface of the first sub-layer; etching the top surface of the first sub-layer to remove substantially all of the non-magnetic segregants accumulated at the top surface; and forming a second sub-layer of the magnetic recording layer on the first sub-layer.
