ABSTRACT:
A heat-assisted magnetic recorder for magnetically recording information onto a recording medium having a given recording coercive field includes an electron beam generator and a magnetic recording head. The electron beam generator directs an electron beam onto the recording medium in order to locally heat a portion of the recording medium such that the heated recording medium portion has a recording coercive field lower than the given recording coercive field. The magnetic recording head generates a magnetic recording field having an intensity greater than the recording coercive field of the heated recording medium portion in order to magnetically record information onto the heated recording medium portion. The electron beam generator includes a plurality of carbon nanotubes (CNTs) embedded in nanoholes of an anodic alumina template for generating the electron beam. A heat-assisted magnetic recording method is associated with the heat-assisted magnetic recorder.
