Abstract
A disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a hardfile disk. Disks are moved into and out of the texturing process in cassettes, through two disk-handling stations. Control of the tool is achieved using a right-side disk handling and processing controller, a right-side cassette handling controller, a left-side disk handling and processing controller, and a left side cassette handling controller. The two disk handling and processing controllers share hardware resources performing the texturing process.
