摘要
A nano-magnetic head for inputting and outputting magnetic signals with nano-region precision on a magnetic recording medium such as magnetic tapes, magnetic cards, magnetic disks, magnetic drums, etc. The nano-magnetic head uses a nanotube with its base end portion fastened to a holder that is at an end of an AFM cantilever. The tip end portion of the nanotube protrudes from the holder, and a nanocoil is wound around the outer circumference of the tip end portion of the nanotube so that signals are inputted and outputted at both ends of the nanocoil. By way of lining up ferromagnetic metal atoms in the hollow portion of the nanotube, it is possible to strengthen the magnetic signal. The nano-magnetic head is combinable with a signal controller, thus forming a nano-magnetic head device.
