Monolithically Fabricated Hybrid Head for Near-Field Assisted Magnetic Recording

Abstract: In this paper, we show a monolithically fabricated hybrid head with a GaAs-based laser diode capable of near-field-assisted magnetic recording. A bottlenecked conductor was placed beside the laser cavity formed on the trailing side of the head. The bottlenecked structure is used as a generator of magnetic and near fields. The structure consists of a couple of opposite electrodes with a 200-nm gap and a bridge connection between the electrodes. The magnetic field is mainly generated around the bottleneck by fee… Show more

“…Near-field assisted magnetic recording (NAMR) 1) is proposed to overcome the limitation of magnetic recording density. Magnetic recording media utilized for the NAMR are required to have enough recording resolution, and the patterned media technology which is eagerly examined in the field of magnetic recording 2)-5) is a powerful candidate.…”
