Disc drive having electromagnetic biased shieldless CPP reader

A method of manufacturing a read head comprising the steps of:

• depositing a first electrical contact layer over a trailing edge surface of a slider body;
• building a read sensor having first and second major side surfaces and a bottom sensor surface on the first electrical contact layer, the read sensor being in direct contact with the first electrical layer;
• building a bias magnet at a spacing above a top edge of the read sensor, the bias magnet being electrically isolated from the first electrical contact layer;
• depositing a non-electrically conductive non magnetic material in the spacing and remaining portion of a layer defined by the bias magnet and the read sensor;
• and
• depositing a second electrical contact layer on the layer defined by the bias magnet and the read sensor, the second electrical contact layer being electrically isolated from the bias magnet, and in direct contact with the read sensor.

A storage device comprising:

• a storage means for storing data, having a read head disposed on a trailing edge of a slider body, the read head having a plurality of layers and configured to fly over the storage means, the read head comprising:
• a read means for reading data stored in the storage means;
• biasing means for biasing the read means;
• a first current carrying means for carrying a current from a current source to the read means, the first current carrying means comprising a non-magnetic electrically conductive material;
• a second current carrying means for carrying a current from the read means to the current source, the second current carrying means comprising a non-magnetic electrically conductive material;
• and
• wherein the current flowing in the read means flows perpendicular to the layers.
