Patent ID: 8416646

Claim:
A magnetic recording disk drive slider having a disk-facing surface and comprising: an optical waveguide having a generally rectangularly-shaped light-emitting output end at the disk-facing surface, the waveguide output end having a thickness in a first direction and a width in a second direction orthogonal to the first direction and greater than the thickness in said first direction, and wherein there is no near-field transducer (NFT) on the slider; a write head having a write pole tip at the disk-facing surface with a trailing edge spaced from the waveguide output end in the first direction, the pole tip having a width in the second direction less than the width of the waveguide; and a read head having a sensing edge at the disk-facing surface and spaced from the waveguide output end in the first direction on the side of the waveguide opposite the write pole tip.
