ABSTRACT:
An improved disc protector assembly which enables a disc to be protectively held in a manner so as to retard warpage is disclosed. The disc protector assembly of the present invention comprises a jacket having a plurality of flaps forming elongated ridges along the length thereof. A removable disc protector is inserted in the jacket and holds the disc. The protector comprises a first member disposed between the flaps adjacent the ridges, and a second member having outwardly extending arms. The second member urges the disc into contact with the flaps along the length thereof. By the use of the protector assembly, problems associated with warpage are substantially overcome.
