Abstract: The present invention is directed to a spin valve sensor for use in a data storage system, that is adapted to receive a sense current and produce a GMR effect in response to applied magnetic fields. The spin valve sensor includes first and second ferromagnetic free layers, a spacer layer positioned between the first and second ferromagnetic free layers, and a biasing component. The first ferromagnetic free layer has a magnetization (M1) in a first direction, when in a quiescent (non-biased) state. The second ferromagnetic free layer has a magnetization (M2) in a second direction that is anti-parallel to the first direction, when in a quiescent (non biased) state.

Abstract: A coding framework that provides conversions between one or more video formats without the use of a transcoder. A video information stream that includes color information formatted in accordance with a first color space sampling format is split into a base stream and an enhanced stream. The base stream is formatted in accordance with a second color space sampling format. The enhanced stream includes enhanced information that when combined with the base stream re-constructs the first format. During encoding, the enhanced stream may be encoded using spatial information related to the base information stream. An output stream of the encoded base stream and encoded enhanced stream may be interleaved, concatenated, or include independent files for the encoded base stream and the encoded enhanced stream.

Abstract: A spin valve sensor for use with a data storage system includes free and pinned ferromagnetic (FM) layers, a conducting layer therebetween, contact leads, free layer biasing elements, and an anti-ferromagnetic (AFM) layer. The pinned layer has opposing ends, which define a width of an active region of the spin valve sensor having a giant magnetoresistive effect in response to applied magnetic fields. The free layer is positioned below the pinned layer and has opposing ends that extend beyond the active region. The contact leads abut the pinned layer and overlay portions of the conducting layer. The free layer biasing elements abut the ends of the free layer and bias a magnetization of the free layer in a longitudinal direction.

Abstract: A magnetoresistive (MR) sensor for use in a magnetic storage system including a magnetic storage media having multiple concentric microtracks with information stored thereon. The MR sensor includes a plurality of generally parallel layers that form an MR stack. The MR sensor also includes a top shield and a bottom shield that are spaced apart on opposite sides of the MR stack in a longitudinal direction. The Mr sensor further includes a first and a second side shield spaced apart on opposite sides of the MR stack in a transverse direction. The top shield, bottom shield, first side shield and second side shield substantially surround the MR stack.

Abstract: A vehicle lamp of which lamp chamber is formed by a lamp body and an outer lens, and a light source and an inner lens are provided inside the lamp chamber, with the inner lens functioning to selectively transmit the complementary color to the color of the outer lens and a desired color and being disposed between the light source and the outer lens. A half mirror is provided on the inner lens so as to face the outer lens.

Abstract: Side-reading of an abutted-junction magnetic transducer is measured by constructing at least one microtrack having a transition density. The transducer is moved relative to the microtrack to identify a plurality of positions of the transducer relative to the microtrack where the transducer provides a predetermined response. The side-reading distance of the transducer is identified from the plurality of positions. In one embodiment, a plurality of microtracks are constructed during different iterations, each having a different transition density, and the positions of the transducer are identified during each iteration relative to the respective microtrack. In another embodiment, the selected transition density has a fundamental frequency, and the position of the transducer is identified relative to the microtrack where the transducer provides the predetermined response at each of a plurality of harmonic frequencies of the fundamental frequency.

Abstract: A magnetic sensor and method for making the sensor are disclosed. The sensor includes a giant-magnetoresistive sensing layer having a ferromagnetic free layer and a hard bias layer to maintain the free layer in a single-domain state or to stabilize the free layer. The hard bias layer has a coercivity of at least 2,000 Oe and a magnetic remnance times thickness at least twice the value of the saturation magnetization times thickness of the free layer. The hard bias layer includes a permanent magnetic layer formed on top of a seed layer made of the alloy TiW or other similar alloys. The seed layer may also be a bi-layer having a layer of TiW or ther similar alloys and a layer of soft magnetic material, with the former in contact with the permanent magnetic layer.
