See-D Discoveries not only has CD and DVD duplication. Cassette duplication is still very important to us. With the wide spread use of Compact Disc and DVD not every one has converted to that format to date. With that being said, we offer both high speed bin duplication and real time duplication as well as custom rolled blank cassettes up to 110 minutes in length. Our contact page has all the information on how to get in touch with See-D Discoveries.
