<p>PURPOSE:To make visual recognition of information stored in a card easy by a method wherein a liquid and magnetic powder afloat in the liquid and sensitive to a magnetic field are contained in microcapsules arranged in a recording layer laid by coating on a base of a magnetic display section. CONSTITUTION:A magnetic display medium 1 is equipped with an information storage section 4 and a magnetic display section 10 that are laid on a base. The information storage section 4 is made up of a magnetic tape or an IC memory, and the magnetic display section 10 has a base and a recording layer containing microcapsules that is laid by coating directly, or through an intermediate layer, on the base. A liquid and magnetic powder that is afloat in the liquid and sensitive to a magnetic field are contained in the microcapsules. The information is recorded, in accordance with the information stored in the information storage section 4, in a visible form in the recording layer of the magnetic display section 10, and is erased from the layer.</p> |
