Abstract
A display and record medium includes a digital information record section, which is implemented as an IC memory and can record record information in noncontact, and an information display section implemented as a liquid crystal display medium of light write type into which display information can be written. A digital information rewrite section of an information writer communicates with the digital information record section of the display and record medium by electromagnetic waves to rewrite record information as required. A display information rewrite section of the information writer irradiates an optical pattern to the information display section of the display and record medium to rewrite display information. It is possible to rewrite both digital information and display information concurrently in noncontact.
