ABSTRACT:
An optical disk recording and reproducing apparatus for recording and reproducing information and which is capable of storing a large amount of information, transferring data at a high speed and supporting SCSI-1 and SCSI-2. The magnetooptical-disk recording and reproducing apparatus is of the same size as that of the 5.25-inch magnetic disk recording and reproducing apparatus. 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. The magnetooptical-disk recording and reproducing apparatus can record information of 1 GB/side or above on the disk.
