Abstract:
A thermomagnetic recording and reproducing head comprising:a recording-use magnetic head for applying a signal magnetic field according to information to be recorded to a recording portion of a recording layer of a thermomagnetic recording medium heated to a recording temperature during recording;a reproducing-use magnetic head for detecting a magnetic flux generated according to recorded information from the recording portion of the recording layer of the thermomagnetic recording medium heated to a reproduction temperature during reproduction; anda heating head with a width narrower than said recording-use magnetic head and reproduction-use magnetic head, for heating the recording portion of the thermomagnetic recording medium to the recording temperature during recording, and to the reproduction temperature during reproduction, wherein the reproduction temperature is less than the Curie temperature of material comprising the recording layer of the thermomagnetic recording medium.
