ABSTRACT:
In a magnetic recording and reproduction apparatus wherein signals are recorded with a ring-type magnetic head to a magnetic recording medium having axis of easy magnetization oblique with respect to a film normal of a magnetic layer of the medium A recording magnetic field generated by the magnetic head is asymmetric with respect to a center line of a gap of the magnetic circuit, and the recording magnetic field in the magnetic layer around a leading edge of the magnetic head is inclined at the same side as the axis of easy magnetization in the magnetic field in a normal plane of the magnetic layer including a direction of relative movement of the magnetic head to the magnetic recording medium when signals are recorded to the medium. Thus, signals can be recorded at a high density. Various types of magnetic head for generating asymmetric magnetic field are provided.
