の誤記録防止機構。[Scope of claim for utility model registration] A recordability detection hole drilled through the upper and lower halves of a disk cartridge in which a recordable and erasable double-sided optical disk is stored, and an operation for opening and closing the recordability detection hole. and an erroneous recording prevention member that prevents erroneous recording and erroneous erasure of recording signals recorded on the optical disk by distinguishing whether recording is possible or not. An operation member facing the operation side and colored in a complementary color to the disk cartridge, and a detection member facing the detection side of the recordability detection hole and colored in a similar color to the disk cartridge. A mechanism for preventing erroneous recording of disk cartridges.
