• We report that a unique reliable process for manufacturing a 28 mm small disk for the blue-ray optical recording system has been developed successfully. To prevent the severe axis run-out, a stepped metal hub for magnetic chucking is directly inserted into the punched-center of a 0.6 mm thick disk. Instead of the conventional laser initializer, we make a new type of UV disk initializer, using Xe-type UV-lamps, which is expected to increase the productivity of rewritable optical disks, due to the short initialization time. Furthermore, the modified dynamic tester makes it possible to analyze small blue-ray disks effectively.
