INFORMATION STORAGE DEVICE USING MAGNETIC DOMAIN WALL MOVING

摘要

An information storage apparatus using magnetic domain wall movement is provided to increase recording density and reduce power consumption by forming the magnetism magnetic track for data storage with ferromagnetic substance having the vertical magnetic anisotropy. An information storage apparatus using magnetic domain wall movement comprises a magnetic track(200) having a plurality of magnetic domains, a current application unit connected to the magnetic track, and a read/write unit(25). The magnetic track includes a zigzag type storage track(T1) having a plurality of first magnetic layers which are laminated in parallel at certain intervals and a second magnetic layer interconnecting the first magnetic layers.
