20150179193 | MULTIPLE READERS FOR HIGH RESOLUTION AND SNR FOR HIGH AREAL DENSITY APPLICATION - The present invention generally relates to a read head in a magnetic recording head. The read head utilizes two reader elements that are stacked in the down track direction within the same read gap to improve resolution and SNR by combining the signals from the two reader elements. The output waveform from each read element is asymmetric in the down track direction; however, by use of equalizer settings and waveform combining the algorithm in signal processing, the combined waveform has a similar or better resolution and higher SNR compared to a single read element in a smaller read gap. | 2015-06-25 |

20150179195 | RECESSED ANTIFERROMAGNETIC DESIGN WITH ANTIPARALLEL PINNED STITCH LAYERS FOR IMPROVED PINNING FIELD - In one general embodiment, a device includes an antiferromagnetic layer; a first stitch layer exchange coupled with the antiferromagnetic layer, the first stitch layer having a magnetic orientation substantially parallel to a magnetic orientation of the antiferromagnetic layer; a second stitch layer exchange coupled with the first stitch layer and having a magnetic orientation substantially antiparallel to the magnetic orientation of the first stitch layer; a pinned layer structure exchange coupled with the second stitch layer; a free layer; and a spacer layer between the free layer and the pinned layer structure. An end of the antiferromagnetic layer facing a sensing face of the device is recessed from the sensing face. | 2015-06-25 |
20150179196 | HEAD GIMBAL ASSEMBLY - A head gimbal assembly includes a suspension board with circuit, a pair of piezoelectric elements mounted on the suspension board with circuit to be expandable/contractible, and a slider on which a magnetic head is mounted and which is mounted on the suspension board with circuit and configured to be able to swing with expansion/contraction of the pair of piezoelectric elements. The pair of piezoelectric elements are placed on the suspension board with circuit such that a first imaginary line extending along an expanding/contracting direction of one of the piezoelectric elements crosses a second imaginary line extending along an expanding/contracting direction of the other piezoelectric element. | 2015-06-25 |
20150179197 | HAMR HEAD SPOT-SIZE CONVERTERS WITH SECONDARY INDEX CONFINEMENT - The present invention generally relates to a HAMR head having not only a tapered core for the SSC, but additionally a secondary confinement material in the cladding surrounding the core taper. The secondary confinement material prevents diverging light from the laser diode from spreading so that the light is coupled into the core of the SSC. The secondary confinement material is a symmetric structure that surrounds the core of the SSC on all sides so that high conversion efficiency is achieved for short taper lengths. | 2015-06-25 |
