            Application No. 08/131,332                                                                   

            Tadokoro et al.          4,908,809               Mar. 13, 1990                               
            (Tadokoro)                                                                                   
            Kato et al.              4,970,618               Nov. 13, 1990                               
            (Kato)                                                                                       
            Ishii                    5,206,844               Apr. 27, 1993                               

                  Claims 5, 6, 9 through 12 and 16 through 18 stand rejected                             
            under 35 U.S.C. '  103.  As evidence of obviousness, the examiner                            
            cites Tadokoro with regard to claims 5 and 6, adding Nemoto with                             
            regard to claims 9 through 12 and applying Tadokoro together with                            
            Kato with regard to claims 16 through 18.                                                    
                  Reference is made to the briefs and answers for the                                    
            respective positions of appellants and the examiner.                                         
                                                OPINION                                                  
                  We reverse.                                                                            
                  We agree with the examiner that Tadokoro clearly teaches a                             
            disk cartridge with a cartridge casing, an overwrite type                                    
            magneto-optical disk and a magnetic initializing means, as set                               
            forth in independent claims 5, 9, 11, 12 and 16, as well as the                              
            yoke comprising an upper arm and a lower arm arranged as recited                             
            in independent claims 5, 9, 11 and 12.                                                       
                  However, the subject matter of each of the independent                                 
            claims differs from that taught by Tadokoro in that which is                                 
            recited in the last paragraph in each claim.  The examiner                                   
            recognizes these differences but contends that the claimed                                   


                                                    3
