PROBLEM TO BE SOLVED: To provide a silicon substrate by which floating height of a magnetic recording head can be made lower than before, satisfactory magnetic anisotropy can be obtained in a magnetic recording film and high recording density can be attained. SOLUTION: In a manufacturing method of the silicon substrate having a texture for a magnetic disk, the texture is formed on the surface of the silicon substrate by using texturing selected from the group consisting of (1) texturing of at least two steps using loose abrasive grain slurry including abrasive grains of different raw materials and/or tapes of different materials, (2) texturing of at least two steps using different working pressures and (3) texturing of at least two steps using loose abrasive grain slurry including abrasive grains of different raw materials and/or tapes of different materials and using different working pressures.
