ABSTRACT:
A magnetic recording head includes a head body having an end divided into two parts, the two parts facing each other with a predetermined distance therebetween, first and second poles that are disposed on the two parts of the head body, respectively, to form a magnetic path and that face each other with a predetermined gap therebetween, and an anisotropic medium that is interposed between the first and second poles and has a magnetic anisotropy. A magnetic field going into the predetermined gap decreases so as to be induced in the predetermined magnetic recording direction.
