          Application No. 08/048,117                                                  


                    detecting means for determining an amount of                      
               light reflected from an optical disc and outputting                    
               a total light amount signal corresponding to the                       
               amount of reflected light;                                             
                    table means for generating reciprocal data which                  
               is a reciprocal of the total light amount signal                       
               output from said detecting means; and                                  
                    a D/A converter to which said tracking and                        
               focusing error signal is supplied as its reference                     
               signal, and said reciprocal data is supplied as its                    
               digital input, with the D/A converter outputting the                   
               normalized error signal.                                               


               The abstracts relied on by the patent examiner in

          Kenzo et al. (Kenzo)     63166318                 Nov. 14, 1988             
          (Patent Abstract of Japan)                                                  
          Maruta                   59-113531                June 30, 1984             
          (Patent Abstract of Japan)                                                  
          Yasuaki                  63124228                 Oct. 12, 1988.

               Claims 1, 5, and 6 stand rejected under 35 U.S.C. §                    
          102(b) as anticipated by Fumiaki.  Claim 2 stands rejected                  
          under 35 U.S.C. § 103 as obvious over Fumiaki in view of
