Title:
DISK PRODUCING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/082550
Kind Code:
A1
Abstract:
A disk producing method has a step of applying a coating material (w) on a disk (D) in rotation and drying the coating material to form coating (W) on the disk substrate (D), a step of detecting the movement of the boundary between a dried region and a not-yet-dried region of the coating (W) in rotation, a step of measuring a coating thickness distribution of the coating (W) after it is dried, and a step of controlling the number of rotation of the disk substrate (D) based on a relationship between the detected movement of the boundary and the coating thickness distribution.
