ABSTRACT:
A magnetic recording head includes a spin wave oscillator having a lamination film including a first magnetic layer and a second magnetic layer, and a pair of electrodes adapted to inject a current between the first magnetic layer and the second magnetic layer to generate a spin wave in one of the first magnetic layer and the second magnetic layer; and a recording magnetic pole provided on one side with the spin wave oscillator, the spin wave oscillator locally heating the recording track prior to recording by the recording magnetic pole.
