Abstract
A protective jacket for permanently containing a floppy-type magnetic recording disk includes a liner attached to at least one of the interior sidewalls of the jacket in a manner whereby a protruding warp is formed in the liner having the form of an elongated ridge. The warp protrudes far enough from the interior wall of the jacket so that, upon rotation of the disk, the warp is deformed and resiliently wipes the face of the disk to remove dust and the like, thereby preventing errors in reading/writing upon the disk.
