Abstract

A changer apparatus for information discs includes a stacking unit for stacking at least two information discs in at least two stacking positions, the stacking unit having holding trays for holding the information discs in holding planes and a first transport mechanism for moving the holding trays into the stacking positions. The holding trays each have a top part and a bottom part, the top parts and the bottom parts of the holding trays are jointly movable in the same direction by means of the first transport mechanism for the transport of the information disc inside the stacking unit, and the top part and the bottom part, of the holding tray holding the information disc to be read and/or inscribed, are movable with respect to one another by means of the first transport mechanism in order to bring this information disc into a play position intended for reading and/or inscribing it, in such a manner that a clearance is obtained between the information disc and the top part and/or between the information disc and the bottom part.
