  • Publication number: 20100318140
    Abstract: The present teachings provide methods of preparing an anode for use in a high volumetric energy density electrolytic capacitor. A lead wire is de-oxidized and sintered in a valve metal powder compact to form the anode. The de-oxidizing and sintering are conducted in the presence of a reactive metal having a stronger affinity for oxygen than the valve metal powder. A residual reactive metal and at least one reactive metal reaction product are removed from the anode surface with a leaching process. Remaining residual reactive metal and reactive metal reaction products are redistributed by thermal processing. A capacitor containing the anode has an operating voltage greater than 90% of the forming voltage.

  • Publication number: 20100274307
    Abstract: Methods of preparing an electrode are provided. A metal lead wire is pre-treated to facilitate bonding of the lead wire to a metal powder during subsequent de-oxidation sintering. A connection region can be formed by directly contacting the metal lead wire with a liquid reactive metal. After removal of resultant oxides, an additional metal powder can be de-oxidation sintered onto the connection region to form the electrode. The oxides formed during the de-oxidation sintering are then removed from the electrode.

  • Patent number: 7068030
    Abstract: A magnetic field strength detector includes a magnetic field sensing element that outputs voltage as a function of magnetic field strength. In some embodiments, the magnetic field sensing element comprises a coil, and voltage is induced across the coil as a function of the magnetic field strength. A magnetic field strength detector also includes an indicator that alters as a function of the voltage output by the magnetic field sensing element when the magnetic field strength exceeds a threshold. The alteration is substantially irreversible and, in some embodiments, visible. The detector may be used to, for example, measure the strength of a magnetic field generated by a degaussing device, or to confirm that a particular medium was exposed to a magnetic field with a strength adequate to degauss the medium.

  • Patent number: 6953629
    Abstract: Perpendicular magnetic media are described for use in magnetic recording and data storage. Seed layer compositions are described which can facilitate perpendicular magnetic anisotropy in subsequently deposited magnetic layers. In particular, nickel-iron-chromium (NiFeCr) alloys or nickle-chromium (NiCr) alloys can be used as seed layers which cause a subsequently multi-layered magnetic stack to assume perpendicular magnetic anisotropy. In this manner, high perpendicular magnetic anisotropy can be achieved and storage densities of media may be increased.

  • Publication number: 20020067683
    Abstract: Playback transducers for patterned media systems comprise temperature sensitive resistors, including thermistors and resistance temperature detectors. The transducers are typically thin film depositions mounted on a slider for flying head application. Possible configurations are generally V-shaped, may involve parallel or perpendicular recording geometry, and are conceptually similar to (but simpler in construction than) magnetoresistive or giantmagnetoresistive thin film transducers. The transducers may incorporate supplementary heating elements and/or coatings to optimize performance.

  • Patent number: 6278592
    Abstract: A giant magnetoresistive spin valve read sensor includes a bilayer seed layer and a stack of films. The bilayer seed layer includes a TaN seed layer and a NiFeCr seed layer. The stack of films includes a free layer adjacent the NiFeCr seed layer, a pinning layer, a pinned layer positioned between the free layer and the pinning layer, and a spacer layer positioned between the free layer and the pinned layer. The bilayer seed layer is used to promote the texture and grain growth of each of the layers subsequently grown upon the seed layer. The free layer has a rotatable magnetic moment, while the pinned layer has a fixed magnetic moment. The resistance of the giant magnetoresistive spin valve read sensor varies as a function of an angle formed between the magnetization of the free layer and the magnetization of the pinned layer.

  • Patent number: 6098880
    Abstract: A magnetoresistive element has a height that extends from the air-bearing surface of a head. The height is determined by a slot in the head extending from the air-bearing surface adjacent the sensor portion at an acute angle to both the air bearing surface and the height of the magnetoresistive element to separate the magnetoresistive element into the sensor portion and a dormant portion. Alternatively, the height is determined by a recess of design depth in the magnetoresistive element at the air bearing surface. Alternatively, the height of the magnetoresistive element is determined by a stepped thickness to the first and second bias current carrying contacts along the height of the magnetoresistive element.

  • Patent number: 6030556
    Abstract: Optical disc stampers, methods of manufacturing the optical disc stampers, systems for manufacturing the optical disc stampers, and methods of replicating optical discs using the stampers are disclosed. The optical disc stamper is formed directly on a substrate that supports a patterning material including at least one layer of a first material and at least one layer of a second material. The first and second materials can include a metal and semiconductor. The patterning material is exposed to energy in selected areas. Unexposed areas of the patterning material are then removed, resulting in an optical disc stamper. The first and second materials can form an amorphous alloy in the exposed selected areas that remains after removal of the unexposed patterning material. The optical disc stamper can be used in the replication of optical data storage discs. Also disclosed arc systems for practicing the methods to produce optical data storage disc stampers.

  • Patent number: 5993930
    Abstract: A dual layer pre-recorded optical disc includes a transparent substrate, a partially reflective layer, a transparent spacer layer, and a highly reflective layer. One pattern of data pits is provided on the substrate, adjacent the partially reflective layer, and another pattern of data pits is provided on the spacer layer, adjacent the highly reflective layer. The transparent spacer layer comprises at least two sublayers. The partially reflective layer may be made of silicon carbide. A substrate-incident beam can be used to read data encoded in either data pit pattern depending on which layer the laser is focused upon. The dual layer disc has twice the data storage capacity of conventional single layer discs.
