ABSTRACT:
The present invention provides magnetic recording heads which utilize higher order excitations of dynamic magnetization to increase frequency without the necessity of biasing the write yoke. In accordance with the present invention, the size and placement of current-carrying microstrip waveguide(s) and write pole(s) are controlled in order to generate spin wave write modes. During writing operations, the magnetization is driven into higher order spatial spin wave modes.
