Abstract: A disk case comprised of a rectangular outer case member being opened at its upper side and made from soft synthetic resin sheet and an inner case member made from soft material selected from non-woven fabric, cloth, paper or synthetic resin sheet to receive a data disc, which is fitted in the outer case member. In order to prevent a received disc from slipping out, one side of the inner case member is fastened to the outer case member forming a space for receiving the words card or words note between the outer case member and inner case member and a stopper formed in the upper end of the outer case member to prevent the disc from slipping out. In order to make the taking in or out of the words card or words note smoothly, the outer case member further provides a cut-off portion at one longitudinal side, thereby allowing a words card or words note to pass therethrough.
