               Representative claim 1 is reproduced below:                            
               1.  A data cartridge exchange apparatus for a data storage             
          system, comprising:                                                         
               a drawer sized to receive a data cartridge;                            
               a first guide rail having a first configuration mounted to             
          said drawer;                                                                
               a guide rail having a second configuration, said guide rail            
          having the second configuration being sized to engage said first            
          guide rail having the first configuration;                                  
               a second guide rail having the first configuration mounted             
          to the data storage system, said second guide rail having the               
          first configuration being sized to engage said guide rail having            
          the second configuration so that said drawer can be moved between           
          a retracted position and an extended position;                              
               a cartridge magazine sized to be received by said drawer,              
          said cartridge magazine being sized to receive the data                     
          cartridge; and                                                              
               a cartridge magazine alignment apparatus mounted to the                
          data storage system, said cartridge magazine alignment apparatus            
          engaging said cartridge magazine when said drawer is in the                 
          retracted position and holding said cartridge magazine in a                 
          registration position.                                                      

               The following references are relied on by the examiner:                
          Ishikawa                 5,644,445           July  1, 1997                  
          Cirocco                  5,951,132           Sep. 14, 1999                  
                                        (filing date Nov. 18, 1997)                   
               Claims 1, 18 and 21 stand rejected under 35 U.S.C. § 103.              
          As evidence of obviousness, the examiner relies upon Ishikawa in            
          view of Cirocco.                                                            

                                          2
