| 20110076784 | Fabrication of Magnetic Element Arrays - Techniques for fabricating an array of magnetic elements to form memory and other devices with a high areal density. | 03-31-2011 |
| 20110102948 | METHOD AND SYSTEM FOR PROVIDING DUAL MAGNETIC TUNNELING JUNCTIONS USABLE IN SPIN TRANSFER TORQUE MAGNETIC MEMORIES - A method and system for providing a magnetic junction usable in a magnetic memory are described. The magnetic junction includes first and second pinned layers, first and second nonmagnetic spacer layers, and a free layer. The first pinned layer has a first pinned layer magnetic moment and is nonmagnetic layer-free. The first nonmagnetic spacer layer resides between the first pinned and free layers. The free layer resides between the first and second nonmagnetic spacer layers. The second pinned layer has a second pinned layer magnetic moment and is nonmagnetic layer-free. The second nonmagnetic spacer layer resides between the free and second pinned layers. The first and second pinned layer magnetic moments are antiferromagnetically coupled and self-pinned. The magnetic junction is configured to allow the free layer to be switched between stable magnetic states when a write current is passed through the magnetic junction. | 05-05-2011 |
| 20110141804 | METHOD AND SYSTEM FOR PROVIDING DUAL MAGNETIC TUNNELING JUNCTIONS USABLE IN SPIN TRANSFER TORQUE MAGNETIC MEMORIES - A method and system for providing a magnetic junction usable in a magnetic memory are described. The magnetic junction includes first and second pinned layers, first and second nonmagnetic spacer layers, and a free layer. The pinned layers are nonmagnetic layer-free and self-pinned. In some aspects, the magnetic junction is configured to allow the free and second pinned layers to be switched between stable magnetic states when write currents are passed therethrough. The magnetic junction has greater than two stable states. In other aspects, the magnetic junction includes at least third and fourth spacer layers, a second free layer therebetween, and a third pinned layer having a pinned layer magnetic moment, being nonmagnetic layer-free, and being coupled to the second pinned layer. The magnetic junction is configured to allow the free layers to be switched between stable magnetic states when write currents are passed therethrough. | 06-16-2011 |

| 20090168268 | Dedicated noncorrosive smear detector - A disk drive head slider for a magnetic disk drive is provided. The head slider includes a tunnel magnetic resistance device for reading data on a magnetic disk and a dedicated noncorrosive smear detector for measuring resistance wherein the resistance corresponds to a level of smear associated with the head slider. | 07-02-2009 |

| 20080247086 | Method for forming interleaved coils with damascene plating - A method of forming interleaved coils of a write head is disclosed using a combination of non-damascene and damascene processes. | 10-09-2008 |
| 20100163523 | FORMATION OF LOW RESISTANCE DAMASCENE COILS - In one embodiment and method of the present invention, a coil of a write head is created by forming a P1 pedestal layer and a back gap layer and further forming a coil pattern consistent with the coil to be formed and insulator spacers dispersed in the coil pattern, using a non-damascene process, thereafter the coil is formed by plating using a damascene process. | 07-01-2010 |
