An ink jet recording apparatus that includes ink with including fine particles and the apparent viscosity being changeable apparently by receiving an electric field, and a voltage applying unit for forming the electric field to make the ink walls. The ink walls are formed by lining up the fine particles in the ink. The ink walls make ink flow channels to flow and discharge ink to form image on a recording medium based on the recording information.

A magnetic recording layer for storing information is formed on the lower surface of a card, and a protective film is formed on the magnetic recording layer. Permanent information, e.g., the valid term of the card and the name of a user, and variable information, e.g., card use history information, are magnetically recorded on the magnetic recording layer. A printed layer is formed on the upper surface of the card. Permanent information such as the valid term of the card and the name of the user is printed on the printed layer. A braille portion indicating purpose of the card in braille is formed on the upper surface of the card.
