Abstract
A record package includes a disc record housed within an enclosure. The enclosure comprises thin membrane covers held in tension between a metallic outer frame and two inner rings. The inner rings include dust seals which are held against the disc record by the tension of the membranes. When the disc record rotates, the windage it creates lifts the dust seals from the disc record. The use of a clear membrane eliminates the need for a sight window when recording on the playing back from an optical disc record.
