A case for machine readable disks, such as DVDs and the like. The case preferably comprises a plastic base and cradle for storing the disk. The cradle may have a central protrusion for securing the disk in the cradle. A liner may be adhered to the bottom of the base. The liner preferably comprises a pair of stop tabs. A pair of sleeves are preferably located on either end of the base. The sleeves are positionable from a closed position to an open position. Locking panels or tabs located within the sleeves engage the stop tabs of the liner when moving the sleeves from the closed to the open position, preventing the sleeves from sliding off the end of the base when the case is being opened. Locking panels or tabs of the sleeves also engage the stop tabs when moving the sleeves from the open to the closed position, preventing the sleeves from sliding beyond approximately the mid-point of the cradle along the base.
