ABSTRACT:
An optical disk recording and/or reproducing apparatus is provided which is capable of storing a large amount of information, transferring data at a high speed, supporting SCSI-1 and SCSI-2, and the reducing the size of the apparatus, particularly the height (to the so-called half height), The magnetooptical-disk recording and/or reproducing apparatus of the invention is of the same size as that of the 5.25-inch magnetic disk recording and/or reproducing apparatus of half height, or it is 146 mm wide, 203 mm deep, and 41.3 mm high. The front panel 1 has the cartridge slot 2 and cartridge ejection button 3 provided thereon so that a cartridge including a disk for recording and reproducing information is inserted in or ejected from the apparatus. The cartridge insertion slot 2 has a double flap provided so that at least one part of the double flap closes the slot, preventing dust from entering through the cartridge slot 2 except when the cartridge is inserted in or ejected from the apparatus, According to this invention, the magnetooptical-disk recording and/or reproducing apparatus can record information of 1 GB/side or above on the disk and has the size of half height.
