  • Patent number: 9715889
    Abstract: A magnetic read apparatus has a media-facing surface (MFS) and includes a read sensor, a magnetic bias structure and an insulating layer. The read sensor has a side, a front occupying part of the MFS and a back. The read sensor includes a free layer, a pinned layer and a barrier layer between the free and pinned layers. The barrier layer has a barrier layer coefficient of thermal expansion. The magnetic bias structure is adjacent to the side of the free layer. The insulating layer includes first and second portions. The first portion of the insulating layer is between the read sensor side and the magnetic bias structure. The second portion of the insulating layer adjoins the read sensor back. The insulating layer has an insulating layer coefficient of thermal expansion that is at least ? of and not more than 5/3 of the barrier layer coefficient of thermal expansion.

  • Patent number: 9087527
    Abstract: A read transducer having a first read sensor, a second read sensor, and a first middle shield is provided. The second read sensor is disposed in a down track direction from the first read sensor. The first middle shield is disposed between the first read sensor and the second read sensor. The first middle shield includes a first metallic middle shield layer disposed between the first read sensor and the second read sensor, a second metallic middle shield layer disposed between the first metallic middle shield layer and the second read sensor, and a first magnetic-spacer layer disposed between the first metallic middle shield layer and the second metallic middle shield layer. The first metallic middle shield layer and the second metallic middle shield layer have substantially the same polarity.

  • Patent number: 7521915
    Abstract: An apparatus adapted to detect a particle present on a bevel of a wafer. The apparatus includes a substrate support and a sensor housing adapted to receive an edge of the wafer. The sensor housing includes one or more probe electrodes and one or more position sensors. The apparatus also includes a translatable stage coupled to the sensor housing. The translatable stage is adapted to control the distance between the bevel of the wafer and the one or more position sensors. The apparatus further includes electrical circuitry electrically coupled to the substrate support and the one or more probe electrodes and adapted to generate an electric field between the bevel of the wafer and the one or more probe electrodes, detection circuitry electrically coupled to the electrical circuitry, and a processor adapted to process electrical signals and thereby detect the particle present on the bevel of the wafer.
