ABSTRACT:
A magnetic head for use in a magnetic recording apparatus for magnetically recording information in a state of heating and elevating the temperature of a recording portion of a recording medium by emitting electrons to the recording medium, the magnetic head including a recording magnetic pole having a magnetic surface opposed to the recording medium, and supplying a magnetic flux to the recording medium and an electron emitting source formed in the recording magnetic pole. The electron emitting source has a concave portion having an opening formed in the recording magnetic pole and open to the recording magnetic pole surface and a bundle of a plurality of carbon nanotubes each extending from the bottom to the opening of the concave portion.
