    In a hybrid recording system, the coercivity is dependent on temperature, and an external laser can locally reduce its value to a point where the field from the magnetic head is sufficient to switch the magnetization and this occurs only where this area crosses the magnetic field from the head. The rectangle waveguide near field optical spot and the recording media heat effect have been studied. The results indicate that the rectangle waveguide near field heating technology can break superparamagnetic limit.
