ある。The operation of the developing neck for optical disk masters constructed as above will be explained below using the drawings. As shown in FIG. 3, cleaning is performed before and after rinsing in the developing process. This is to clean the optical disk master by rotating the turntable rotation motor 16 while dripping or spraying cleaning liquid such as water from the cleaning liquid discharge port 18. In this case, the support rotation motor 21 is repeatedly rotated left and right. By turning the cleaning liquid discharge port horizontally as shown in FIG. 2, the entire surface of the optical disk master is cleaned. Further, by making the tip of the cleaning liquid discharge port thinner as shown in FIG. 4, the cleaning liquid discharge pressure is increased and the cleaning ability is further increased. Pre-cleaning before development removes heavily adhered dust and dirt, and post-cleaning after development completely removes the developer that was not removed by rinsing.
