Claim:
1. A magnetic recording medium manufacturing method comprising: forming a bonding layer containing first metal on a substrate; forming a holding layer containing silicon on the bonding layer; forming a roughness inhibition layer between the bonding layer and the holding layer, which is made of carbon, and which includes a plurality of openings; forming a single-particle layer on the holding layer using particles containing second metal bondable in a solid state on the bonding layer; etching silicon dioxide with an etching solution containing hydrofluoric acid and hydrogen peroxide solution and embedding the holding layer with the particles until the particles are brought into contact with the bonding layer, the silicon dioxide being formed by oxidation reaction of the holding layer under catalysis of the second metal in a region that contacts the particles; bonding the particles and the bonding layer together by heating; and forming a magnetic recording layer on the single-particle layer.
