  • Thermal venting device with pressurized plenum
    Patent number: 10037062
    Abstract: A thermal venting device is provided that includes a plenum including an inlet port and a plurality of outlet ports, the plenum being substantially fluidically sealed except for the inlet port and the plurality of outlet ports, the inlet port including an inlet fan configured to pressurize the plenum, each of the plurality of outlet ports being configured to direct airflow from the pressurized plenum toward different electronic components of a plurality of electronic components, and each of the plurality of outlet ports including respective resistive elements having varied airflow resistances configured to bias airflow through the plurality of outlet ports.

  • Recording head writer with high magnetic moment material at the writer gap and associated process
    Patent number: 7688545
    Abstract: A magnetic recording head with an overall planar design and tight dimensional control of throat height and notch width is achieved below the gap. Writer poles include very high magnetic moment material on both sides of the writer gap. Additionally the pole tips are shaped to provide high field with good spatial gradient for optimal writing conditions, thereby extending the capability of longitudinal recording heads for high density and high frequency applications.

  • Side shielded current in plane spin-valve
    Patent number: 7130165
    Abstract: The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnetically decoupled from the hard bias materials by placement of spacers.
