2. Description of the Related Art It is generally known to display recorded contents and other information on a recording medium. In this case, most of the information is displayed on a paper such as a label. On the other hand, in recent computer technology, in order to enhance the listability of information in a recording medium, content display by characters and images such as directories and icons is generally used.

FIG. 16 shows an example of a conventional disc-shaped recording medium. 17 and 18 show an example of a conventional storage case for a recording medium. FIG. 17 shows a case containing one sheet, and FIG.
Indicates a case containing multiple sheets. Further, FIG. 19 shows an example of a conventional recording / reproducing apparatus. Reference numeral 71 is a recording medium, and 72 is a main recording medium unit. 83 and 9
Reference numeral 2 is a portion for housing the recording medium 71. Reference numeral 101 is a conventional recording / reproducing apparatus, and 102 is a recording / reproducing unit.

In the prior art, a label 73 is attached to the recording medium 71.
It is common to paste. Further, a piece of paper is put in the cases 81 and 91, or labels 82 and 93 are attached to the cases 81 and 91.

On the other hand, recently, the technology for display elements has advanced, and a display element has been developed which can display an arbitrary image or character and can maintain the display with no power consumption or low power consumption. Has been done. Examples of such a display element include polymer-dispersed liquid crystal, ferroelectric liquid crystal, and electrophoretic element.
