ABSTRACT:
A disc recording and/or reproducing apparatus includes a holding device for holding a disc cartridge which is a cartridge main body and a disc housed in the cartridge main body, a rotating and driving device for rotationally driving the disc housed within the holding device, and a positioning device provided within the rotating and driving device for positioning the disc cartridge housed within the holding device. The recording disc may be positioned highly accurately within the disc cartridge in such a manner that resonant vibrations may be prevented from being produced on the chassis.
