摘要:
Embodiments of the present disclosure generally relate to magnetic recording systems, and more particularly to a magnetic recording system with a current-assisted write head. The write head comprises a main pole, a trailing shield disposed above the main pole, a trailing gap disposed between the main pole and the trailing shield, a side shield surrounding three sides of the main pole, the side shield being in contact with and disposed below the trailing shield and the trailing gap, and a side gap disposed between the side shield and each of the three sides of the main pole. The side gap comprises a non-magnetic electrically-conducting material to dissipate heat away from the main pole, lowering the resistance and temperature rise due to heating. The trailing gap may further comprise a non-magnetic electrically-conducting material. The write head may have a two terminal or three terminal connection configuration.
