| 20100020437 | SINGLE-PASS RECORDING OF MULTILEVEL PATTERNED MEDIA - A method of performing data/information recording and retrieval utilizing a multilevel patterned magnetic medium, comprises providing a magnetic recording system including a read/write head and a multilevel patterned magnetic recording medium including a plurality of spaced apart data/information storage elements each comprising a stacked plurality n of magnetic recording cells with different magnetic properties and magnetically decoupled from overlying and/or underlying cells; providing relative movement between the write head and magnetic recording medium; and writing to the medium by supplying the write head with a modulated write current comprising a plurality n of pulses of different magnitudes while the head passes over each element, thereby applying n different magnetic field strengths to each element, the write current including a first pulse of magnitude sufficient to write to a first cell of each element having a highest magnetic coercivity of said cells, and n−1 succeeding pulses of progressively smaller magnitude for sequentially writing to the remaining n−1 lower magnetic coercivity cells of each element but of insufficient magnitude to write to progressively higher magnetic coercivity cells, such that the writing occurs in a single pass of the write head over each element. | 01-28-2010 |
| 20100046118 | TIME-SHIFTED BITS FOR WRITE SYNCHRONIZATION CORRECTION - Systems and methods are provided for correcting write synchronization of a magnetic storage device with respect to magnetic storage media and its corresponding writable magnetic bits, or dots. In particular, these systems and methods involve using time-shifting principles to calibrate the magnetic storage devices to correct slow drifts of reader-writer timing. It is to be appreciated that time-shifting techniques can be applied in a variety of manners. For example, the very dots on the media can be positioned in time-shifted fashion. In another example, the writing to the dots can be time-shifted. | 02-25-2010 |

| 20100165508 | MAGNETIC LAYERING FOR BIT-PATTERNED MEDIA - A perpendicular magnetic recording layer of a magnetic recording medium includes a plurality of bit-patterned magnetic islands, wherein each of the plurality of islands overlay a soft magnetic under-layer. Each of the magnetic islands includes a first magnetic sub-layer adjacent a second magnetic sub-layer, wherein the first sub-layer has a relatively high magnetic anisotropy that is greater than a magnetic anisotropy of the second sub-layer. The magnetic recording layer further includes a third sub-layer, which extends to connect each of the plurality of islands. The third sub-layer may have a magnetic anisotropy that is less than that of the second sub-layer of each of the magnetic islands and/or may serve as an interlayer, extending between the first sub-layer and the soft magnetic under-layer of the recording medium, and having a structure to help to produce the greater anisotropy first magnetic sub-layer. | 07-01-2010 |

| 20100209737 | MAGNETIC RECORDING MEDIA WITH ENHANCED WRITABILITY AND THERMAL STABILITY - Aspects are directed to recording media with enhanced magnetic properties for improved writability. Examples can be included or related to methods, systems and components that allow for improved writability while reducing defects so as to obtain uniform magnetic properties such as uniformly high anisotropy and narrow switching field distribution. Some examples include a recording medium with an exchange tuning layer inserted between the hard layer and the soft, semi-soft or thin semi-hard layer so as to maximize the writability improvement of the media. Preferably, the exchange tuning layer is granular and reduces or optimizes the vertical coupling between the hard layer and the soft, semi-soft or semi-hard layer of a magnetic recording or storing device. | 08-19-2010 |

| 20100073809 | X-AMR ASSISTED RECORDING ON HIGH DENSITY BPM MEDIA - A method of writing information to an area of a bit-patterned medium, in which a magnetized probe generates a magnetic probe field at the area of bit-patterned medium to be written, applying an oriented static magnetic field, and applying an oriented microwave field at a selected frequency, resulting in the writing of information onto the area of bit-patterned media. | 03-25-2010 |
| 20100215846 | GRANULAR PERPENDICULAR MAGNETIC RECORDING MEDIA WITH DUAL RECORDING LAYER AND METHOD OF FABRICATING SAME - A granular perpendicular magnetic recording medium comprises a non-magnetic substrate and a granular perpendicular magnetic recording layer overlying the substrate, comprising a first granular perpendicular magnetic layer proximal the substrate and having a first saturation magnetization (M | 08-26-2010 |

An exemplary embodiment of the method comprises extracting a set of extracted data from the plurality of data sources and processing at least a portion of the extracted data with a set of knowledge agents according to specific criteria to create at least one data assemblage. The exemplary method also comprises providing an integrated two-dimensional/three-dimensional (2D/3D) visual display in which at least one 2D element of the at least one data assemblage is integrated into a 3D visual representation using a mapping identifier and a criteria identifier. | 02-24-2011 |
| 20110063292 | Systems and Methods For Connectivity Analysis Using Functional Objects - Systems and methods which utilize functional objects in connectivity analysis are shown. Functional objects may be denoted by a geological feature, a user-defined location, a critical point in a connection network, a region within a 3D volume, etc. Each functional object preferably possesses and/or has associated therewith an ability to obtain information such as relevant connection pathways, linked regions of interest, statistical connection information, etc. Such functional objects may have dynamic regions associated therewith, such as to define an area of uncertainty, for facilitating exploring connectivity. Desired connectivity information can be revealed interactively from within a confusing web of connection pathways through use of the functional objects. Through interactive manipulation of functional objects analysis may be refined or revised. Additionally or alternatively, logical operations may be applied with respect to one or more functional objects to extend or reduce the connectivity of interest. | 03-17-2011 |
