A method of manufacturing a disc-like recording medium for use in magnetic, optical, opto-magnetic recording/reproducing devices which are capable of recording still image information and/or reproducing recorded still image information, and a disc-like recording-medium. A center core forming the recording medium is to be carried during the assembling process thereof in such a manner that the other portions of a plate-shaped resilient member than the support point thereof are provisionally secure to a core block by use of an adhesive or that a projection piece section provided in the plate-shaped resilient member is inserted into a recessed portion formed in the peripheral surface of a center hole in the core block so as to be able to secure the projection piece section. Due to this, the plate-shaped resilient member can be prevented from getting out of the core block and also the forces of the plate-shaped resilient member can be maintained at a constant level.
