A disk cartridge includes a cartridge casing comprised of upper and lower shells attached along the peripheral edges thereof so as to define a disk receiving space within the cartridge casing. The casing structure is formed with an insert opening for allowing a data disk to be easily inserted into an operating position within the assembled cartridge casing. A slide area which may be formed as a recessed surface portion, or the like, is defined at corresponding outer peripheral portions of the upper and lower shells. A disk access opening is formed in the casing shells at a location within the slide area for allowing a head portion of a disk drive to perform read and write operations to the disk. A slidable shutter is mounted astride the upper and lower shells at and edge of the cartridge casing, within the slide area. The shutter portion maybe biased by a spring, or the like so as to normally close the disk access opening while being slidably movable so as to open the disk access opening during disk operation. The cartridge structure further includes a cover portion including a hinge formed on one or both of the casing shells. The cover is openably and closably enabled via the hinge and includes locking means so as to securely close the cartridge casing in a closed position of the cover. According to this, a data disk may be rotatably installed within the cartridge casing in a separate step after assembly of the cartridge casing. As a result of this structure, quality control is also simplified. Accordingly, manufacturing defects are minimized and overall costs and reduced. In addition, waste generated by disposal of defective products is reduced.
