A disc protecting cover for preventing a disc used as an information recording medium from being damaged or wounded while the disc is not in use, which comprises a flat portion (11;11A) having a diameter smaller than that of a disc which is provided with a center hole and a signal reading surface portion formed on a part of the surface thereof extending around the center hole, and an engaging portion (12) projecting from a central part of the flat portion (11'11A) and adapted to be inserted into the center hole of the disc to engage with the same. The flat portion (11;11A) covers the signal reading surface portion of the disc when the engaging portion (12) is inserted into the center hole of the disc to engage with the same. The disc protecting cover is attached to the disc to be detachable therefrom and can reliably protect the signal reading surface portion of the disc against damage or wound without covering portions of the disc which are not required to be covered therewith.
