Card including rotary recording medium sheet

Abstract

Abstract PURPOSE:To obtain a card with a high recording density and a large storage capacity by inserting a rotary recording medium sheet into a flat space between coating materials and providing a connecting part, which is connected to an external rotation driving source, in the rotation center part of this sheet and forming apertures for write and read on coating materials. CONSTITUTION:A card body 1 consists of a pair of coating materials 1a and 1a of flat square plates and a frame-shaped spacer member 1b and includes a freely rotatable recording medium sheet 2, and apertures 3 for write and read are formed on surfaces of the body 1 and are closed with transparent sheet materials 4. The sheet 2 has a disc shape, and a connecting part 11 which is connected to the external rotation driving source is attached to its rotation center part. The connecting part 11 has a non-circular hole 12.
