It has been disclosed with respect to the hybrid recording and reproducing head for high density recording. The disclosed head is writing data on a recording medium, and in the hybrid recording and reproducing head having a member for reproducing data from the recording medium on the slider back side, members for the recording and reproducing is to be the data of the recording medium data playback for reproducing data from the magnetic field applying means and the recording medium for applying a magnetic field to write the data on the area heated by the energy supplied from the energy source, the energy source for supplying energy for heating the region but it characterized in that it comprises means, prevents the magnetic field applying means is the channel having we can deliver the energy supplied from said energy source to said region, completely surrounding the channel the transfer of heat to the therearound from the channel and member, is characterized in that the heat transfer preventing member is completely surround the pole for data recording (pole) and consisting of a magnetic field generating means for generating a magnetic field in the pole for the data recording. With this invention, data recorded in the process due to the heat transferred from the channel data recording for the pole (pole) and the magnetic sensitive sensor and the like may can be prevented from being functionally damage increase the reliability for data recording and reproduction have. In addition, by narrowing the possible area in which the focusing is heated by the energy beam reaches the data recording area of ​​the recording medium, the data recording density can be increased.
