Process and device for coating disc-shaped data storage media

A device for coating disc-shaped data storage media (8) with a coating medium, said device comprising:

• a rotatable support for the storage medium (8);
• at least one coating nozzle (1) comprising a drive unit (5, 6) for moving said at least one coating nozzle (1) across the storage medium (8) to a location of application (12) of the coating medium;
• wherein said drive unit (5, 6) is a hydraulic arrangement with a first hydraulic cylinder (5 or 6) for a first movement (9) and a second hydraulic cylinder (6 or 5) for a second movement (11) of said at least one coating nozzle (1), said first hydraulic cylinder (5 or 6) moving the coating nozzle (1) across the storage medium (8) to a first location (10) and said second hydraulic cylinder (6 or 5) acting counter to said first hydraulic cylinder (5 or 6) at said first location (10) to slow the at least one coating nozzle (1) until it reaches the preselected application location (12) above the storage medium (8) where said at least one coating nozzle (1) is stopped:
• and
• wherein said first movement (9) is effected at a speed that is greater than a speed of the second movement (11).
