THERMALLY-ASSISTED MAGNETIC RECORDING HEAD INCLUDING A MAGNETIC POLE AND A HEATING ELEMENT
摘要:
A thermally-assisted magnetic recording head includes a magnetic pole and a heating element. The magnetic pole has a front end face located in a medium facing surface. The magnetic pole forms on a track a distribution of write magnetic field strength that peaks at a first position on the track. The heating element forms on the track a distribution of temperature that peaks at a second position on the track. The first position is located on the trailing side relative to the second position. The front end face of the magnetic pole has a main portion and first and second extended portions. The first and second extended portions are extended in the track width direction from the main portion at positions on the leading side relative to the center of the main portion in the direction of travel of a magnetic recording medium.
