    • A method and system for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser are described. The laser provides energy. The EAMR transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The EAMR transducer includes a near field transducer (NFT) proximate to the ABS for focusing the energy onto the region of the media. The method and system include providing a heat sink having a bottom thermally coupled with the NFT and a top surface at an angle with respect to the ABS. The angle is greater than zero and less than ninety degrees. The method and system also include providing a write pole and at least one coil. The write pole is configured to write to a region of the media. The write pole has a bottom surface thermally coupled with the top surface of the heat sink. The at least one coil is for energizing 24.
    • 描述了一种用于提供与激光器耦合的能量辅助磁记录(EAMR)传感器的方法和系统。 激光器提供能量。 EAMR传感器具有配置成在使用期间驻留在介质附近的空气轴承表面(ABS)。 EAMR传感器包括靠近ABS的近场传感器(NFT),用于将能量聚焦到介质的区域上。 该方法和系统包括提供具有与NFT热耦合的底部和相对于ABS成一定角度的顶表面的散热器。 角度大于零,小于九十度。 所述方法和系统还包括提供写极点和至少一个线圈。 写入极配置为写入介质的一个区域。 写极具有与散热器的顶表面热耦合的底表面。 至少一个线圈用于激励24。
