摘要: The present disclosure provides for a magnetic writer pole for use in a hard drive. The magnetic writer pole comprises a first bevel formed by a non-magnetic layer, the first bevel formed at a first angle and extending to a first throat height. The magnetic writer pole further comprises a second bevel formed by the non-magnetic layer and extending distally from the first bevel at a second angle that is greater than the first angle and extending to a second throat height. The magnetic writer pole further comprises a third bevel formed by the non-magnetic layer and extending distally from the second bevel at a third angle that is greater than the second angle.

摘要: A heat assisted magnetic recording (HAMR) write transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use and is coupled with a laser that provides energy. The HAMR transducer includes a main pole, at least one additional pole adjacent to the main pole in a down track direction, a waveguide and at least one coil for energizing the main pole. The main pole is configured to write to a region of the media and is recessed from the ABS by a first distance. The additional pole(s) are recessed from the ABS by a second distance greater than the first distance. The waveguide is optically coupled with the laser and directs a portion of the energy toward the ABS at an acute angle from the ABS. A portion of the waveguide resides between the additional pole(s) and the ABS.
