ABSTRACT:
A disc cartridge and a disc drive apparatus. The disc cartridge includes an upper case and a lower case which form an internal space to accommodate a disc, and a pair of elastic protrusions formed at both sidewalls of the lower cases, which are elastically biased toward the internal space so that ends of the elastic protrusions support the disc. Surfaces are formed at the ends to slope toward the internal space so that the disc is located in an upper portion of the internal space and the pair of elastic protrusions supports the disc. The disc descends on the surfaces when the pair of elastic protrusions are opened and the disc is then located in a lower portion of the internal space.
