Patent ID: 7903374

Claim:
A magnetic recording and reading device which comprises: a perpendicular magnetic recording medium; a perpendicular magnetic head comprising a recording head having a heat-generating portion which enables heating of the perpendicular magnetic recording medium, and a reading head provided with a read element having a track width of not more than 0.9 μm; a fine adjustment portion for correcting a position of the perpendicular magnetic head; and a R/W-IC; wherein the perpendicular magnetic head is configured to perform magnetic recording of information on the perpendicular magnetic recording medium by application of a magnetic field from the magnetic head while the heat-generating portion of the perpendicular magnetic head locally heats the perpendicular magnetic recording medium by control of the R/W-IC so as to enable a change of the coercive force of the perpendicular magnetic recording medium during the information recording after correcting of the position of the perpendicular magnetic head by the fine adjustment portion is completed, and to perform reading of the magnetic recording information with the aid of the reading head by control of the R/W-IC after correcting of the position of the perpendicular magnetic head by the fine adjustment portion is completed.
