ABSTRACT:
A disc changer device includes a housing section, a transporting unit, a recording and/or reproducing unit and a movement unit. The housing section houses a number of discs, such as compact discs, with a pre-set distance between neighboring discs, in a state in which disc surfaces face one another. The transport unit holds one of the discs in the housing section from the direction of disc thickness for transport between it and the recording and/or reproducing unit. The recording and/or reproducing unit records and/or reproduces the disc transported from the housing section by the transporting unit. The movement unit moves at least one of the discs positioned in the housing section and held by the transporting unit in a direction away from the disc held by the transporting unit when holding the disc from the direction of disc thickness out of the housing section by the transporting unit and/or when returning the disc by the transporting unit into the housing section.
