Abstract
A disc drive device for holding plural discs of different sizes in stable state such as to provide a sufficient recording area for each disc. In addition, the disc drive device is adapted for setting the discs of different sizes accommodated in cartridges of different thicknesses at a predetermined height in order to run the disc in the cartridge in stability. With the disc drive device, turntables 31, 32 for rotatably holding the discs vary the holding areas for the discs depending on the disc size.
