摘要:
According to one embodiment, a magnetic head includes a main pole, a write shield magnetic pole opposed to the main pole with a write gap, and a high-frequency oscillator provided between the main pole and the write shield magnetic pole within the write gap. The main pole includes a shield-side end surface opposing the write shield magnetic pole with the write gap and brought into contact with the high frequency oscillator. The high-frequency oscillator has a width in a cross-track direction, in an air bearing surface, greater than a width of the shield-side end surface in the cross-track direction. The high-frequency oscillator is disposed to extend over at least one end edge of the shield-side end surface in the cross-track direction to an outer side of the main pole.
