               Appeal No. 96-1346                                                                                                    
               Application 08/122,611                                                                                                


               tracking control and track discrimination pits 70, 71 disposed in the servo control area for                          

               discriminating between odd and even tracks.  The examiner indicates that each wobble pit is between                   

               two tracks and is shared by both tracks as a wobble pit on an outer circumferential side of one of the                

               adjacent recording tracks and as a wobble pit on an inner circumferential side of the other of the                    

               adjacent recording tracks which is situated at an outer circumferential side of the one of the adjacent               

               recording tracks.  The examiner’s answer acknowledges that Sugiyama does not teach pairs of wobble                    

               pits with no information therebetween as information area 69 is positioned between wobble pits 7 and                  

               8.  However, the examiner asserts that Verboom teaches such an arrangement of wobble pits.                            

                       Appellant contends that the combination of Sugiyama and Verboom fails “…to result in an                       

               optical disk having an adjacent pair of wobble pits and a track discrimination pit in the same servo                  

               control information area.”  It is urged that “Sugiyama relies on a determination of whether the pre-pit               

               pair 7 or pre-pit pair 8 precedes the other for generating a track inversion signal (see col. 10, lines 26-           

               41) and not on a track discrimination pit”.  Appellant asserts that pre-pits 70 and 71 of Sugiyama                    

               cannot function as the track discrimination pits of the claimed invention and only give header information            

               including even or odd track identification after tracking is achieved.                                                

                       Inasmuch as appellant does not challenge the prior art rejection of claims 2, 7 and 9-19 with                 
               any reasonable specificity, these claims fall with apparatus claim 1 .2                                               

               2Although appellant separately argues method claim 2 in the main brief at the paragraph bridging pages 5 and          
               6, the argument is in effect the same as made with respect to apparatus claim 1.                                      
                                                                 4
