The data disc type can be discriminated in utilizing a part of control information or using through holes (52-54) of disc cassette (51), and even in the case where the magneto-optical disc is loaded erroneously, the desired data can be recorded/reproduced on the corresponding disc selectively by shifting the operation as occasion demands. And thus, even in the case where this type of magneto-optical disc is used for data recording, the magneto-optical disc device and the magneto-optical disc which are capable of simplifying the disc control can be obtained. <IMAGE> |
