摘要 | A head stack assembly includes a mounting base, a plurality of drive arms connected with the mounting base, and multiple pairs of head gimbal assemblies connected with the drive arms. Each head gimbal assembly includes a thermal assisted magnetic head, the thermal assisted magnetic head has an air bearing surface, a bottom surface opposite to the air bearing surface, and a laser diode module mounted on the bottom surface and adapted to emit a downward laser light to a write element of the thermal assisted magnetic head and an upward laser light, wherein a light shielding structure is provided to prevent the upward laser light emitting to other laser diode modules to generate light coupling, thereby improving thermal stability of the thermal assisted magnetic head. |
其他摘要 | 头堆组件包括安装基座,与安装基座连接的多个驱动臂,以及与驱动臂连接的多对头万向节组件。每个磁头万向节组件包括热辅助磁头,热辅助磁头具有空气轴承表面,与空气轴承表面相对的底表面,以及安装在底表面上并适于发射向下激光的激光二极管模块热辅助磁头的写入元件和向上的激光,其中提供光屏蔽结构以防止向上激光发射到其他激光二极管模块以产生光耦合,从而提高热辅助磁头的热稳定性。 |
