ABSTRACT:
A cooling station for data carrier disks, in particular for injection-molded substrates of optically readable data carriers, such as CD, CD-R, DVD, CD single, DVD single and the like, has at least three rotatable cooling spindles which are arranged in spaced-apart parallel relationship such that a substrate bears simultaneously upon all cooling spindles. Each cooling spindle has at least two threads with thread grooves of different width to thereby accommodate in the same cooling station, e.g. CD substrates and DVD substrates. As an alternative, or in addition, four or more cooling spindles may be provided and arranged in such a manner that respectively three cooling spindles are provided for transport of substrates with a particular substrate diameter. In this way, substrates of different diameter, e.g., standard CD and CD single, can be accommodated in a same cooling station.
