    • PROBLEM TO BE SOLVED: To facilitate the discrimination of a signal surface and the taking-out/ in of a recording medium by providing a slope on the outer peripheral side surface of the recording medium, providing a projection on the upper part of a title surface, making the notch of an internal CD fixing part into half and providing CD pressing parts upward/downward. SOLUTION: The slope of elevation angle of about 45 deg. is made to the outer peripheral side surface of a recording medium such as a CD in a state of making a signal surface downward. A round projection is provided on the upper part of a title surface in a preservation case in a state of making an opening/ closing part a right side, the half of the notch of a CD fixing part 6 in the inside of the case is eliminated and the CD pressing parts 7 are provided upward/downward in the inside. When the recording medium is taken out, it is constituted so that upper/lower, left/right are confirmed by the round projection, are opening/closing part is opened to be lifted up and the CD pressing parts are released to take out the recording medium. Thus, the signal surface of the recording medium is discriminated easily by feeling, a load to the CD fixing part in the preservation case is reduced, a fall is prevented by the CD pressing parts and the recording medium can be dealt in stably.
