| 20090136782 | MAGNETIC RECORDING MEDIA HAVING A CHEMICALLY ORDERED MAGNETIC LAYER - A thin film structure having a magnetic layer and a seed layer positioned adjacent to the magnetic layer is provided. The seed layer includes a L1 | 05-28-2009 |
| 20090142621 | CHROMIUM NITRIDE LAYER FOR MAGNETIC RECORDING MEDIUM - A magnetic recording media with a multilayer structure and methods for forming the media are described. The magnetic recording media includes a substrate, an underlayer on top of the substrate and a magnetic layer over the underlayer. The underlayer includes a CrN film formed by sputter depositing chromium in the presence of nitrogen or nitrogen containing compounds. | 06-04-2009 |
| 20100110577 | Composite Heat Assisted Magnetic Recording Media With Temperature Tuned Intergranular Exchange - A thin film structure including a plurality of grains of a first magnetic material having a first Curie temperature embedded in a matrix of a second material having a second Curie temperature, wherein the second Curie temperature is lower than the first Curie temperature and the second material comprises one or more of an oxide, a sulfide, a nitride, and a boride. | 05-06-2010 |
| 20100129685 | RECORDING MEDIA WITH REDUCED MAGNETIC HEAD KEEPER SPACING, HEAD MEDIA SPACING, OR HEAD TO SOFT UNDERLAYER SPACING - Aspects include recording media with enhanced areal density through reduction of head media spacing, head keeper spacing, or head to soft underlayer spacing. Such aspects comprise replacing currently non-magnetic components of devices, such as interlayers and overcoats with components and compositions comprising magnetic materials. Other aspects relate to magnetic seed layers deposited within a recording medium. Preferably, these aspects, embodied as methods, systems and/or components thereof reduce effective magnetic spacing without sacrificing physical spacing. | 05-27-2010 |
| 20100214684 | Discrete Track Media (DTM) Design and Fabrication for Heat Assisted Magnetic Recording (HAMR) - An apparatus includes a recording media including a substrate, a plurality of tracks of magnetic material on the substrate, and a non-magnetic material between the tracks; a recording head having an air bearing surface positioned adjacent to the recording media, and including a magnetic pole, an optical transducer, and a near-field transducer, wherein the near-field transducer directs electromagnetic radiation onto tracks to heat portions of the tracks and a magnetic field from the magnetic pole is used to create magnetic transitions in the heated portions of the tracks; and a plasmonic material positioned adjacent to the magnetic material to increase coupling between the electromagnetic radiation and the magnetic material. | 08-26-2010 |
| 20110020670 | Chromium Nitride Film Layer - In a recording medium, a CrN film layer comprising a B1 phase crystal structure. | 01-27-2011 |
| 20110096432 | Thin Film Structure With Controlled Lateral Thermal Spreading In The Thin Film - An apparatus includes a magnetic layer, a heat sink layer, and a thermal resistor layer between the magnetic layer and the heat sink layer. The apparatus may be configured as a thin film structure arranged for data storage. The apparatus may also include an interlayer positioned between the magnetic layer and the thermal resistor layer. | 04-28-2011 |
| 20110298456 | TUNNELING MAGNETO-RESISTIVE SENSORS WITH BUFFER LAYERS - In certain embodiments, a tunneling magneto-resistive (TMR) sensor includes a sensor stack positioned between a seed layer and a cap layer. The seed layer includes a first buffer layer that includes a non-magnetic nickel alloy. | 12-08-2011 |
