Disk storage case and recording medium

Abstract

The present invention is applied to a disk storage case adapted to store and carry, for example, a disk-shaped recording medium and to the recording medium, wherein the disk-shaped recording medium 21 is clamped and held from one surface and the other surface to be stored to prevent stress from being applied to the relevant recoding medium 21 when the recording medium 21 is stored and removed.

1 . A disk storage case having an approximately box-shaped first case that stores a disk-shaped recording medium and a second case that is pivotally supported by the first case to turn freely and makes the recording medium stored in the first case difficult to be removed by closing an opening of the first case, characterized in that: 
 the first case includes a supporting portion at an interior bottom surface for supporting one surface of the recording medium, and supports the one surface of the recording medium by the supporting portion to oppose the one surface to the interior bottom surface; and    the second case includes clamping and holding means for clamping and holding the recording medium supported by the supporting portion between the supporting portion and itself.    
   
   
       2 . The disk storage case according to  claim 1 , characterized in that: 
 the first case includes case-interior positioning guide means for positioning a storage position inside of the first case for the recording medium.    
   
   
       3 . The disk storage case according to  claim 1 , characterized in that: 
 the first case includes turning-direction positioning means for positioning by restricting the motion of the stored recording medium in a turning direction.    
   
   
       4 . A recording medium formed into a disk shape having a center hole, provided with a recording area on at least one surface, and stored in a predetermined storage case, characterized by including 
 an engagement portion with which positioning means of the storage case is engaged, in a part other than the recording area.    
   
   
       5 . The recording medium according to  claim 4 , characterized in that: 
 the engagement portion is a through hole penetrating from one surface to another surface.    
   
   
       6 . The disk storage case according to  claim 3 , characterized in that: 
 the first case and/or the second case are/is formed of a transparent member, and the disk-shaped recording medium stored in the first and second cases is able to be seen from outside through the first case and/or the second case; and    the turning-direction positioning means is set to be a reference position if a surface of a label described on the disk-shaped recording medium is seen from outside when the disk-shaped recording medium is stored in the case.
