PROBLEM TO BE SOLVED: To provide a method for producing a CoCrPt-SiO<SB>2</SB>sputtering target with a fine structure for depositing a magnetic recording film applied to a high density magnetic recording medium for a hard disk, particularly, for depositing a CoCrPt-SiO<SB>2</SB>granular magnetic recording film applied to a perpendicular magnetic recording medium. SOLUTION: The method for producing a CoCrPt-SiO<SB>2</SB>sputtering target for depositing a magnetic recording film is provided by which a powdery mixture obtained by mixing Pt powder and fine SiO<SB>2</SB>powder is subjected to calcining treatment thereby producing Pt-SiO<SB>2</SB>calcining-treated powder, and the Pt-SiO<SB>2</SB>calcining-treated powder is blended with Cr powder and Co powder, they are mixed, and the obtained powdery mixture is subjected to pressure sintering.
