Protective divider and enclosure disc assembly for laser discs and laser disc drives

Abstract

A substantially circular disc is disclosed for insertion between laser discs outside of a laser disc drive. The disc prevents surface scratching of laser discs. The disc is placed between laser discs outside of a case and between laser discs in laser disc cases, spindle containers, storage files and carrying cases. This invention further incluides a laser disc enclosure for protecting both sides of a laser disc inside and outside a laser disc drive.

I claim;  
     
         1 . An annular protective disc for use with laser discs for insertion between said laser discs outside of a laser disc drive, wherein said protective disc is substantially the same diameter as a laser disc, said protective disc having a radially innermost and radially outermost portion coextensive with the surface of a laser disc, comprising: 
 compressed cotton Pelon, fabric material coextensive with the diameter of said protective disc, having a centrally disposed aperture adapted to receive the spindles of laser disc cases, storage files, spindle containers and carrying cases, said aperture similar to the size of the aperture in a laser disc.    
     
     
         2 . An annular protective enclosure disc for use with laser discs inside and outside of a laser disc drive, wherein said enclosure disc is slightly larger than the diameter of a laser disc, said enclosure disc having a radially innermost and radially outermost portion in a concentric relationship therewith, said radially outermost portion coextensive with the blank or recorded portion of a laser disc comprising: 
 annular clear plastic material coextensive with the diameter of said protective disc, having a centrally disposed aperture larger than the aperture in a laser disc, and    a beveled outside edge slightly larger than the circumference of a laser disc adapted to grip and hold the outer circumference of a laser disc in a tight juxtaposition relationship, to prevent lateral or longitudinal displacement.    
     
     
         3 . The structure set forth in  claim 2  above further including: 
 An annular enclosure disc cover adapted to fit over a laser disc and under the beveled edge of the enclosure disc enclosing a laser disc in a protective disc enclosure, comprising: 
 clear plastic material with a centrally disposed aperture larger than the aperture of a laser disc with a circumference exactly the same size as a laser disc.  
 
 
     
     
         4 . The structure set forth in  claim 3  above, wherein: 
 said means for attachment of said enclosure disc and cover further includes releasable attachment means.  
 
     
     
         5 . The structure set forth in  claim 4  above, wherein: 
 said means for attachment of said enclosure disc and cover further includes permanent electro welding or permanent adhesion.
