P C A and P M A are calculated from the A T I P dedicated information, and the count values recorded in P C A are measured (step 3 G 2). From the count value, the start address of the area on the PCA where the recording test has been performed is known. According to the address, the starting position of the area where the PCA number has been recorded and tested is found (step 3 Q 3), and the sub-code or A T IP address is updated at this starting position (step 3 0 4). -10- This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 mm) ---- 一 丨 ί ----- • Installation -------- Order ----- ---- ^ _ wl (Please read the notes on the back before filling in this page) 476953 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ..
