摘要： The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semicondutor or an antiferromagnetic material against the magnetic layers, and the magneto-resistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.
摘要翻译：磁阻效应元件是至少具有磁性层和抵抗磁性层的绝缘材料，半导体或反铁磁材料的中间层的多层结构，并且磁阻效应元件具有至少形成在相对的磁体上的端子层，使得电流在中间层中流动。构成磁阻效应元件的所有磁性层的膜表面基本上与磁记录介质的记录表面成直角相对。因此，能够极大地降低与磁记录介质的记录面对置的磁性层的面积，因此能够通过电流检测来自高密度记录磁记录介质的非常窄的区域的磁场穿透特性，穿过中间层。
