INFORMATION STORAGE DEVICE AND METHOD OF OPERATING THE SAME

摘要

PURPOSE: An information storage device and a method of operating the same are provided to increase a storage capacity without a rotating machine using the moving principle of the magnetic wall of a magnetic material. CONSTITUTION: An information storage device comprises a magnetic track(100), a recording/reproducing unit, first and second switching elements(T1,T2), and a third switching element(T3), and a circuit unit. The magnetic track includes magnetic domains(D) and magnetic wall domains((DW)) which are formed between the magnetic domains. The recording/reproducing unit is arranged in a first area(R1) of the magnetic track and comprises first and second electrodes(30a,30b) on its both ends. The first and second switching elements are respectively connected to both ends of the magnetic track. The third switching element is connected to the first electrode of the recording/reproducing unit. The circuit unit controls first to third switching elements. The control unit applies current to at least one of the magnetic track and the recording/reproducing unit.
