There is obtained a disk cartridge apparatus in which when a plurality of disk cartridges which are different in size and thickness are loaded on a drive device, the heights of respective switch detection surfaces of disk cartridges can be horizontally aligned with a mode detection switch of the drive device. A disk cartridge apparatus comprises disk cartridges (1) (12) stored within cartridge housings different in size and thickness in which disks having different diameters are stored, mis-erase prevention plugs (44) (49) including mis-erase prevention detection holes (45) (50) having switch detection surfaces (46) (51) on the disk cartridges (1) (12), a cassette compartment (23) including a recording and reproducing portion for loading the disk cartridge (1) (12) to record and/or reproduce the disk, a detection switch (47) (52) disposed on the cassette compartment (23) to detect the mis-erase prevention detection holes (45) (50) and a position reference portion for determining the positions and heights of the disk cartridges on the cassette compartment (23), wherein when the disk cartridge (1) (12) is loaded on the cassette compartment (23), the heights of the respective switch detection surfaces (46) (51) of the disk cartridges can be horizontally aligned with the detection switches (47) (52).
A disk recording/reproducing apparatus for selectively installing therein a first disk cartridge having a first detection hole and being of a first thickness and a second disk cartridge smaller than said first disk cartridge, being of a second thickness less than the first thickness, and having a second detection hole, where a mis-erase protecting plug is slidably positioned between an upper shell and a lower shell of the first disk cartridge and the second disk cartridge, respectively, and opens and closes a mis-erase preventing detection hole of each of the first disk cartridge and the second disk cartridge, where a respective portion of the mis-erase protecting plug disposed through the mis-erase preventing detection hole of each of the first disk cartridge and the second disk cartridge is used as the detection surface for the mis-erase preventing detection hole, the apparatus comprising:
