20150154988 | HEAD GIMBALS ASSEMBLY, METHOD FOR MANUFACTURING THERMAL-ASSISTED MAGNETIC RECORDING AND MANUFACTURING EQUIPMENT OF THERMAL-ASSISTED MAGNETIC RECORDING - Embodiments of the present invention generally relate to a HAMR head. The HAMR head includes an anti-reflecting (AR) coating on a side opposite (e.g., a flex side) of the air bearing surface (ABS). The anti-reflective coating may include one or more anti-reflective layers. The anti-reflective coating reduces the amount of light reflected back towards a light source unit. A shading layer may be disposed on the anti-reflective coating and may function as a contact electrode as well as reducing stray light escaping from the laser, thus reducing the amount of stray light reaching the ABS. | 06-04-2015 |
