Abstract

PURPOSE:To realize a high frequency driving and small-sized and light weight construction, by providing a conductor sheet on a chip or a permanent magnet via an insulated layer and producing magnetic field with electric conduction to the conductor sheet. CONSTITUTION:A memory pattern effective part layer 5 is formed on a magnetic film 4, and a sheet-type conductor layer 7 having an area slightly larger than the effective area of the layer 5 is formed on the layer 5 via an insulated layer 6. In addition, a permanent magnet for bias magnetic field is provided on the layer 7. Then a magnetic field is generated by the magnetic line of force produced by an electric conduction to the layer 7 to transfer the bubble. In such constitution, no external drive coil exists to realize a high frequency drive. Furthermore, it is small- sized and light weighted.
