PURPOSE:To automatically control an interval at the time of joining and to easily execute production by using a transferring mold and executing the production of a disk substrate. CONSTITUTION:The production of a disk substrate 5 is executed by using a transferring mold 20 to have plural recessing parts 6, for which depth H is larger than forming depth (h) of a recording surface forming part 16 and each depth H is made equal, in a spot excepting for the recording surface forming part 16 of a stamper 15 in the disk substrate 5. Thus, when the production of the disk substrate 5 is executed by using the stamper 15, an ultraviolet ray setting resin layer 2 invades into the recessing part 6 in the stamper 15 side by the pressure of the stamper 15 and a projecting part 7 is generated. When the disk substrate 5 is joined, this projecting part 7 and the projecting part 7, which is formed on the opponent side disk substrate 5, play the role of a spacer. |
