Magnetic recording medium and method for manufacturing same, and method for recording and reproducing with magnetic recording medium

A magnetic recording medium is disclosed which eliminates the difficulty of stably forming tiny recording magnetic domains during high density recording. The magnetic recording medium is constituted such that at least a recording layer is provided on a disk substrate, and the recording layer is bonded with hydrogen and is in a localized and stable state of coupling with a rare earth metal, as well as a method for manufacturing this medium. As a result, the magnetic anisotropy of the recording layer is increased and a stable film structure can be formed, which stabilizes the recording magnetic domains even when the mark length is reduced, and greatly increases recording density without reducing the reproduction signal amplitude.
