Thermal-assisted magnetic recording head capable of supressing the temperature rise of scatterer |
摘要 |
The present invention suppresses temperature rise of an optical near-field generator while increasing optical near-field intensity in a thermally assisted magnetic recording head using a conductive scatterer as the optical near-field generator. The present invention uses a conductive scatterer having a cross-sectional shape in which its width is gradually reduced toward an apex where an optical near-field is generated, and also has a shape in which its width is reduced gradually or in a stepwise fashion toward the apex where the optical near-field is generated in a traveling direction of incident light. |
