Magnetic recording and reproducing apparatus

Abstract

A magnetic recording and reproducing apparatus includes a magnetic recording medium including a plurality of magnetic recording layers disposed on a nonmagnetic substrate; and a magnetic recording and reproducing head including a high-frequency magnetic field generating element. The magnetic recording and reproducing head includes a recording pole configured to generate a recording magnetic field for writing information onto the magnetic recording medium. The recording pole has a width within a range between 30 nm and 80 nm in a radial direction of the magnetic recording medium. The high-frequency magnetic field generating element has a width smaller than that of the recording pole. One of the plurality of magnetic recording layers that is closest to the high-frequency magnetic field generating element is a magnetic layer having a granular structure containing isolated magnetic grains including Co and Pt and having an hcp structure with c-axis orientation.
