Abstract
A disc changer apparatus includes a stacking unit for stacking at least two holder compartments, adapted to hold one disc each, in at least two stacking positions. The holder compartments are coupled to at least one spindle having a screwthread and are movable in a vertical direction by rotation of the spindles. The holder compartments are stacked in upper and lower stacking zones of the stacking. The changer apparatus has a play position for reading information stored on the information discs and/or writing information on the informaton discs. A central zone of the stacking unit between the upper and the lower stacking zone has a loading position, into which one of the holder compartments is movable by rotation of the spindles. A transporter unit is adapted to move the disc from the holder compartment, which is in the loading position, into the play and eject positions.
