PROBLEM TO BE SOLVED: To effectively prevent deformation of a cover sheet caused by the influence of remaining distortion in an adhesive film of disk laminated body pressed by a pressing roller, without performing complex control. SOLUTION: A placing plane 44 of a support table 42 is formed by curvature plane curved in a projecting shape along a shift direction of a roller, the placing plane 44 is curved with the prescribed radius of curvature. A shaft center SR of a pressing roller 54 is supported so as to be accurately in parallel to curvature center line LC of the placing plane 44. The disk laminated body 32 placed on the support table 42 is sucked to the placing plane 44 in a close contact manner by the action of negative pressure. The pressing roller 54 rolls on the disk laminated body 32 sucked to the placing plane 44 and placed along a shift direction of the roller, press-contacts to the disk laminated body 32 with fixed pressure, and sticks a cover sheet 24 in the disk laminated body 32 to a disk substrate 12 by an adhesive film 26.
