Cooling method for the substrate disks of optical data media, e.g. CDs during their production, combines support and rotation of the disk by a directed gas jet and transverse guidance and transport using a central holding rod
Cooling method for the substrate disks of optical data media, e.g. CDs during their production, combines support and rotation of the disk by a directed gas jet and transverse guidance and transport using a central holding rod
Method for cooling and conditioning the substrate disk of an optical data carrier that has an inner central hole in which the disk is supported on a gas cushion that is provided by a guided gas flow. The gas flow cools the disk, and sets the disk in rotation, while a holding rod, which engages in the central hole, serves for transverse guidance and transport. An independent claim is made for a device for cooling and conditioning the substrate disk of an optical data carrier that has an inner central hole.
