PROBLEM TO BE SOLVED : To provide a magnetic recording medium for recording and reproducing which secures the stability of recorded information and is excellent in signal characteristics even in high density recording.
SOLUTION : A magnetic recording medium is constituted such that at least a recording layer 15 is provided on a disk substrate 11, and the recording layer 15 is bonded with hydrogen and is in a localized and stable state of coupling with a rare earth metal, and a method for manufacturing the medium is provided. As a result, the magnetic anisotropy of the recording layer 15 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.
