Magnetic recording and reading device |
摘要 |
A magnetic recording and reading device includes a perpendicular magnetic recording medium, a perpendicular magnetic head having a recording head width having a heat-generating portion and a reading head, a fine adjustment portion, and a R/W-IC. The perpendicular magnetic head is configured to perform magnetic recording on the recording medium while locally heating the recording medium so as to enable a change of the coercive force of the recording medium during the 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 after correcting of the position of the perpendicular magnetic head by the fine adjustment portion is completed.
