Abstract
A plasmon generator of a thermally-assisted magnetic recording head has a first configuration member having a near-field light generation end surface at an ABS, and a second configuration member being in contact with main magnetic pole, and terminating at a front end portion of a slope positioned at the position recessed from the ABS. An end part of a separator layer, which is interposed between the main magnetic pole and the first configuration member, on a side opposite to the ABS is at a position more recessed from the air bearing surface than the front end portion of the slope of the second configuration member.
