Title:
熱補助磁気記録ヘッド及びその製造方法
Document Type and Number:
Japanese Patent JP4800889
Kind Code:
B2
Abstract:
A heat assisted magnetic recording (HAMR) head and manufacturing method are provided. The HAMR head is mounted on a slider having an air-bearing surface (ABS) and includes a substrate; a recording unit formed on the substrate and having a stepped end; a waveguide located in a space formed by the stepped end; and a near field light emission (NFE) pole located adjacent to the recording unit and having an end located on a same plane as the ABS. The method includes forming a cladding layer on a substrate; forming a first metal layer on the cladding layer; etching a part of the first metal layer; forming a core layer on the etched region; forming a refraction part in a part of the core layer; forming a second metal layer the first metal layer and the core layer; and forming a recording unit on the second metal layer.
