摘要：PROBLEM TO BE SOLVED: To permit to obtain a sensitivity, achievable an excellent error rate in a high recording density. SOLUTION: A reproducing head is provided with a magnetization free layer having two opposing main surfaces and one surface substantially parallel to a medium opposing surface, a non-magnetic layer formed on a surface at the opposite side to the medium of the magnetization free layer so as to be contacted with the magnetization free layer, and a pair of magnetization adhering layers formed on the opposite surface of magnetization free layer of the non-magnetic layer so as to be contacted with the non-magnetic layer and extended outwardly. The reproducing head is constituted so that a sense current is made to flow between the magnetization free layer and the pair of magnetization adhering layers. COPYRIGHT: (C)2004,JPO
