Abstract: A two piece attachment device used for securing a protective shield to a vehicle's head rest poles. The attachment device, as a first piece, includes a pair of shield plates, which include a front plate and a rear plate, attached to opposite sides of the protective shield. The front plate includes a shield attachment screw hole. The attachment device also includes, as a second piece, a head rest pole attachment plate. The attachment plate includes a pair of horizontal pole attachment arms with pole attachment channels. The attachment arms adapted for receipt around a portion of a pair of spaced apart, vertical, head rest poles. The attachment device further includes an “L” shaped shield release plate for attachment to the head rest pole attachment plate. The “L” shaped shield release plate is releasably attached to the front shield plate, using a shield attachment screw received in the shield.

Abstract: A spin valve sensor in a read head has a spacer layer which is located between a self-pinned AP pinned layer structure and a free layer structure. The free layer structure is longitudinally stabilized by first and second hard bias layers which abut first and second side surfaces of the spin valve sensor. The AP pinned layer structure has an antiparallel coupling layer (APC) which is located between first and second AP pinned layers (AP1) and (AP2). The invention employs a resetting process for setting of the magnetic moments of the AP pinned layers by applying a field at an acute angle to the head surface in a plane parallel to the major planes of the layers of the sensor. The resetting process sets a proper polarity of each AP pinned layer, which polarity conforms to processing circuitry employed with the spin valve sensor.
