    Abstract: Various embodiments of a read head employ a bias stack which is in a sensor stack of the read head. The bias stack includes a biasing layer and is separated from a free layer in the sensor by a spacer layer. A magnetic moment of the free layer is longitudinally biased antiparallel to a magnetic moment of the biasing layer because of the coupling therebetween. The free layer is therefore more uniformly longitudinally biased than when hard bias layers are employed at first and second side surfaces of the sensor. Various methods are described for making the various read heads of the present invention.

    Abstract: A magnetoresistive sensor for use in a data storage device has a recessed sensing element (magnetic tunnel junction, CPP spin valve, etc.) with an exchange biased sensing ferromagnetic (free) layer, and a flux guide that magnetically connects the sensing element to a sensing surface of the sensor. The free layer is selectively exchange biased by a layer of exchange bias material placed under non-active regions of the free layer that lie outside the sensing element and flux guide track widths. The flux guide is provided by extending the free layer from a forward edge of the sensing element to the sensor surface. Advantageously, the sensing element and the flux guide have equal track width so that magnetic flux directed from the flux guide into the sensing element is not diluted with consequent loss of sensitivity.

    Abstract: Longitudinal biasing of a free layer in a current perpendicular to the planes of the layers (CPP) type of sensor in a read head is implemented by pinning magnetic moments of first and second side portions of the free layer beyond the track width of the read head with first and second insulating antiferromagnetic (AFM) layers which are exchange coupled thereto. The pinning of the magnetic moments of the first and second side portions of the free layer pin and longitudinally bias the central active portion of the free layer within the track width so that the central portion of the free layer is magnetically stable.

    Abstract: The disclosure relates to a microarray reader that includes a light source which emits light and beam shaping elements positioned near the light source to direct the light. The microarray reader further includes a microarray that is at least formed of an optical substrate and a reaction chamber in contact with the optical substrate. A buffer solution is encapsulated by the optical substrate and the reaction chamber and a holder aligns the microarray relative to the light source such that when light hits the buffer solution molecules in the buffer solution are excited to emit fluorescent light. A temperature control component is thermally engaged with the holder such that the temperature control component adjusts the temperature of the buffer solution. The microarray reader further includes a sensor that receives the fluorescent light emitted by the excited molecules in the buffer solution to generate a signal.
