          Application 08/225,322                                                      

               This is a decision on appeal under 35 U.S.C. § 134 from                
          the final rejection of claims 1, 2, 4-6, 11, 12, and 15.                    
          Claims 3, 7-10, 13, 14, and 16-19 stand withdrawn by the                    
          Examiner as being directed to a nonelected species.                         
               We affirm-in-part.                                                     
                                     BACKGROUND                                       
               The disclosed invention is directed to a driving method                
          and apparatus for an optical read/write drive.                              
               Claim 1 is reproduced below.                                           
                    1.  In an optical read/write device of the type                   
               having a light source element in an optical pickup for                 
               reading and writing data from and to an optical disk, a                
               driving method for said light source element comprising                
               the steps of:                                                          
                    determining whether an abnormal tracking error                    
               occurs based on a tracking error signal generated in                   
               accordance with the movement of the optical pickup; and                
                    supplying the light source element with a drive                   
               signal having a level suitable for a data read operation,              
               independent of the driving mode of the optical pickup,                 
               thereby operating the optical pickup at a power level                  
               suitable for reading data, when an abnormal tracking                   
               error occurs.                                                          

               The Examiner relies on the admitted prior art (APA) at                 
          pages 1-3 of the specification and figure 1, and on the                     
          following prior art:                                                        

                                        - 2 -
