                    The invention is directed to a disk storage cartridge             
          assembly and, more particularly, to such an assembly having a               
          casing with a wear factor associated with sliding contact with a            
                                                -10  3

                    21. A data storage cartridge assembly comprising:                 
                    a data storage medium for storing data thereon in                 
          machine readable form;                                                      
                    a casing for supporting said data storage medium                  
          therewithin and for shielding said data storage medium from                 
          physical contact with other objects; and                                    
                    a door slideably mounted on said casing for selectively           
          covering and uncovering an opening therein;                                 
                         said casing having a wear factor associated with             
                    sliding contact with said door of less than 100x10-10             
                    in -min/ft-lb-hr; and3                                                               
                    said casing being constructed from a thermoplastic                
          material impregnated with a lubricating filler wherein said                 
          lubricating filler comprises at least 15% by weight of said                 
          casing.
