ABSTRACT:
An information storage device includes a magnetic structure having a buffer track and a plurality of storage tracks connected to the buffer track. A write/read unit is disposed on the magnetic structure, and a plurality of switching devices are respectively connected to the buffer track, the plurality of storage tracks, and the write/read unit. The switching devices that are respectively connected to the buffer track and the storage tracks. The information storage device further includes a circuit configured to supply current to at least one of the magnetic structure and the write/read unit.
