| 摘要 |
A high areal recording density longitudinal magnetic recording medium having improved thermal stability and signal-to-medium noise ratio ("SMNR"), comprises:(a) a non-magnetic substrate having at least one surface; and(b) a layer stack overlying the at least one surface, comprising a plurality of vertically spaced-apart ferromagnetic layers, each vertically adjacent pair of ferromagnetic layers being spaced-apart by a respective non-magnetic spacer layer, wherein:(i) at least one of the plurality of vertically adjacent, spaced-apart pairs of ferromagnetic layers forms an anti-ferromagnetically coupled media ("AFC") component of the magnetic recording medium; and(ii) at least one of the plurality of vertically adjacent, spaced-apart pairs of ferromagnetic layers forms a laminated media ("LM") component of the magnetic recording medium.
