An optical disk assembly includes a web assembly having a flexible disk-shaped support web carrying a record layer. The support web has an information storage region. A pair of annular retaining ring members engage opposite sides of an annular peripheral region of the web assembly to clamp the support therebetween are formed from malleable stock material which is deformed during assembly of the optical disk assembly to provide a locking interfit therebetween with the peripheral region of the web assembly interleaved between the ring members. The peripheral region of the support is wrapped about an annular reference surface of one ring member and is pushed into an annular recess with undercut area in that ring member. The other ring member is deformed into the recess undercut.
