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. |

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. |
