ABSTRACT:
A magnetic head is configured so that an aspect ratio w0/h0of a cross section of a coil (11) is set to be 1 to 4, or preferably, approximately 1.5. This configuration suppresses the heat generation in the magnetic head that performs the magnetic field modulation, without impairing the efficiency, thereby making the magnetic head suitable for high-frequency modulation.
