          Appeal No. 1999-2240                                                        
          Application 08/909,349                                                      

          recording layer area being smaller than the data area                       
          available for recording the data (Br16).                                    
               It appears that the Examiner ignores this limitation in                
          the obviousness rejection because of the 35 U.S.C. § 112,                   
          first paragraph, written description rejection.  This                       
          rejection has been reversed and, thus, the limitation must                  
          be addressed.                                                               
               The limitation of "one half of said amount of data to                  
          be recorded on said medium is recorded to a predetermined                   
          data area in said data area of said first recording layer,                  
          said predetermined data area being smaller than said data                   
          area available for recording the data" requires that one                    
          half of the data to be recorded is less than the capacity of                
          the data area of the first recording layer.  This limitation                
          distinguishes over recording data until the first recording                 
          layer is filled and then recording the remainder on the                     
          second recording layer.  Best does not describe how data is                 
          distributed when recorded and, thus, Best does not teach or                 
          suggest recording half the data in a predetermined data area                
          which is smaller than the data area of the first recording                  
          layer.  Accordingly, the Examiner has failed to establish a                 

                                       - 12 -
