Summary:PROBLEM TO BE SOLVED: To obtain a magnetic recording medium having a satisfactory SNR and capable of performing high density recording by forming a magnetic recording layer wherein particles are fine and a particle diameter distribution is small and which has satisfactory crystallinity. SOLUTION: At least three underlayers of a first underlayer constituted essentially of at least one component selected from Ag, Ir, Ni, Pd, Pt, Rh, Hf, Re, Ru, Ti, Ta, Zr, Mg and Al, a second underlayer containing Mg or Al and Si and a third underlayer containing at least one selected from Pt, Pd, Ru, Rh, Co and Ti as a main component are provided between a substrate and the magnetic recording layer.
