ABSTRACT:
A magnetic write/read head for a recording medium to be magnetized perpendicularly is disclosed. The head contains a conduction body for carrying the lines of magnetic flux, two pole legs which are arranged adjacent the other in the direction of relative motion of the head and medium and having a predetermined distance from each other. At least one coil winding is associated with the two pole legs. The magnetic head is of a mechanical design which ensures a switchable write and read function with high efficiency. One of the two pole legs has a region of reduced cross section. A separate coil winding is associated with each pole leg and, for performing the write function, this region can be driven into magnetic saturation by means of a coil winding which is associated with the pole leg having the region of reduced cross section. Additionally, one of the two pole legs may include a region of magnetizable material having a predetermined Curie temperature which can be heated during the write function above the Curie temperature.
