摘要
A write head for a disk drive includes a first layer of magnetic material having a fixed magnetization aligned in a first direction, a second layer of magnetic material having a changeable magnetization aligned in a quiescent state in a second direction orthogonal to the first direction, a first non-magnetic layer positioned between the first layer of magnetic material and the second layer of magnetic material, electrodes for connection to a current supply for passing an electric current through the first layer of magnetic material, the first non-magnetic layer, and the second layer of magnetic material for switching the changeable magnetization of the second layer, and an arm for positioning a first edge of the second layer of magnetic material adjacent to a magnetic recording medium, whereby the magnetization of the second layer of magnetic material affects magnetization of the magnetic recording medium. A method of recording information bits in a magnetic recording medium using the write head is also included.
