Spindle transport and cooling system, for optical disc manufacture, includes four spindles adjusted for simultaneous contact with optically-readable data discs in various formats

摘要

The spindle holder is constructed to allow the relative spatial arrangement of the spindles (1, 1', 2, 2') to be adjusted, such that substrates of differing formats are held by all four spindles simultaneously. A servomotor (18) varies the position of the spindles by driving a toothed belt (16).
