Alignment features for heat assisted magnetic recording transducers |
摘要 |
An apparatus comprises an optical transducer positioned adjacent to a storage medium and including a waveguide and a grating for coupling light into the waveguide, a light source transmitting light to the grating, and a detector for detecting a portion of the light, wherein the detected portion of the light has a magnitude that varies in response to the amount of light coupled into the waveguide. |
