Abstract
The invention concerns a device and a process for applying a lubricant by means of vapour deposition to a target object, especially a magnetic data carrier. The device in accordance with the invention comprises a lubricant supply means () that can be filled from outside, possibly by means of a feed line. The produced lubricant vapour () is expanded through one or more exit openings () in the direction of a target object () on which the vapour deposition is to be effected. The vapour at first becomes adsorbed on the walls of a cone-shaped distribution element () situated between the lubricant supply means () and the target object (), from which it subsequently desorbs again. Said adsorption/desorption process assures an even and homogeneous vapour distribution over the target object (). A device for interrupting the vapour supply makes it possible for the device to be operated in a discontinuous manner.
