Abstract
In a disc cartridge and a disc drive apparatus, a disc cartridge has an identification opening where an identification plate is installed to be capable of sliding. A probing portion is installed at the disc drive apparatus and is turned on or off by interference with the identification opening. Thus, the type of a disc can be identified by the on/off actions, that is, by interference with the identification plate and probing portion.
