The invention relates to a device for aligning a data carrier plate and its drive (11) with respect to a data transmission head in a data transmission device, in which data are read from or written into the data carrier plate by means of light rays, which data carrier plate is arranged with its drive on a carrier (10) which can be aligned with respect to the data transmission head and for this purpose comprises adjustment locations (12, 13, 14) which cooperate with adjustment members (15, 17) and thus define adjustment distances, wherein one of the adjustment members (15) acts on an associated adjustment location (12) on the carrier (10) so as to modify its adjustment, and the contact rods (2) comprise adjustment locations (13, 14) formed by surface deformations in contact regions (8), which adjustment locations (13, 14) cooperate in an adjustment-modifying manner with adjustment members (17) contacting said adjustment locations (13, 14).
