Abstract

PURPOSE:To enable free-malfunction information transfer by reducing unstable and unnecessary magnetic fields, by applying an unnecessary-magnetic-field canceling current by providing an unnecessary-magnetic-field canceling layer. CONSTITUTION:Over a magnetic layer 12 on a substrate 11, a conductor layer 15 is formed across an insulating layer 13 and on the layer 15, a conductive layer 20 forming a conductive layer for driving a minor loop side together with the conductor layer 15 is also formed across an insulating layer 18. On this layer 20, conductive layers 43 and 47 for canceling an unnecessary magnetic field are laminated across similar insulating layers 41 and 45. Similary, conductive layers 44 and 48 for canceling an unnecessary magnetic field are formed over the conductive layer forming conductive layers 17 and 19 for driving a major loop side. When driving currents I1 and I2 are supplied to those conductor layers 15 and 20, supplying currents I1' and I2' for canceling unnecessary magnetic fields to the conductor layers 44 and 48 cancels an unnecessary magnetic field 35, generated in areas corresponding to the conductor layers 17 and 21, with a canceling magnetic field 51, and a similarly an unnecessary magnetic field 35' established in areas corresponding to the conductor layers 15 and 20 is also canceled, preventing erroneous operation of information transfer due to the unnecessary magnetic fields.
