Patent ID: 8416649

Claim:
A method to improve Thermally Assisted Magnetic Recording (TAMR), comprising: providing a single magnetic pole perpendicularly disposed relative to a magnetic recording medium having a first surface; shaping said single magnetic pole to have a planar leading surface that is perpendicular to said first surface; locating a plasmon generator parallel to, and at a first distance, that is in a range of from 10 to 60 nm, from, said leading surface; said plasmon generator serving to generate a hot spot at said first surface; further shaping said single magnetic pole to have an air bearing surface (ABS) that extends away from said leading surface to a terminating edge whose distance t 1 from said leading edge is no more than 50 nm; still further shaping said single magnetic pole to have a trailing surface that begins at said terminating edge and that angles away from said first surface at an angle that is in a range of from 30 to 70 degrees relative to the ABS; and thereby causing a peak in a magnetic field generated by said single magnetic pole to lie within said hot spot.
