             Appeal No. 2005-2584                                                                                     
             Application No. 09/897,331                                                                               


                                                   The Invention                                                      
                    The invention relates to a record carrier, particularly an optically readable disk,               
             which has information marks along tracks which exhibit first variations representing an                  
             information signal recorded on the carrier and second variations caused by variations                    
             associated with the information marks.  The phase of the first variations is coupled to                  
             the phase of the second variations.  See page 2 of appellants’ specification.  The first                 
             variations are in the form of pits formed in a track on the disk, which are optically                    
             detectable, and the second variation are in the form of track undulation also known as                   
             wobble.  See page 5 of appellants’ specification.  The phase of the second variations is                 
             coupled to the phase of the first variations in that a predetermined number of wobbles                   
             corresponds to a predetermined number of channel bits represented by the first                           
             variation.                                                                                               
                    Claim 4 is representative of the invention and is reproduced below:                               
                    4.         A record carrier (1) having information marks along a track (11) thereof               
                    and exhibiting:                                                                                   
                        first variations caused by existence and nonexistence of the information                      
                    marks along the track, said first variations representing an information signal                   
                    recorded on said record carrier, and second variations (W) caused by variations                   
                    associated with the information marks; the phase of the second variations being                   
                    coupled to the phase of the first variations.
