Medium Disc Filing Means and Disc Storage Means Incorporating Same

Abstract

A medium disc filing means comprises a filing rail ( 20 ) and a plurality of detachable disc holders ( 30 ), the filing rail comprises a rail body and a pair of transversally protruding flanges ( 21,22 ), each disc holder comprises an attachment member and a medium disc receptacle, the attachment member comprises a clipping aperture ( 37 ) which is resiliently deformable so that the clipping aperture can be deformed to overcome the transversal width of the pair of flanges when a disc holder is to be attached to or detached from the filing rail. Such a filing means provides improved reliability and convenience since medium discs can be placed at selective locations on the filing rail and a filing order can be reasonably maintained due to clipping engagement between the filing rail and the disc holders.
