Abstract:
A method of fabricating a magnetic recording medium including a non-magnetic substrate having a Young's Modulus greater than that of aluminum (Al) and its alloys and a surface with a preselected average surface roughness (Ra), which method comprises the sequential steps of:(a) depositing a continuous, adherent, non-magnetic, catalytically active layer on said substrate surface; and(b) electrolessly plating an amorphous seed layer comprising a metal, metal alloy, or metal compound on said catalytically active layer, the Ra of the resultant surface of said amorphous seed layer being reduced from said preselected Ra of said substrate surface, thereby providing a substantially defect-free surface for deposition thereon of layer(s) comprising said magnetic recording medium.
