A magnetic card incudes a magnetic layer, a bar code, a protection layer, and a pseudo bar code. The magnetic layer is formed on a substrate, records magnetic information, and reflects light. The bar code is formed on a predetermined area of the magnetic layer by a light absorption material and detected by no generation of reflected light from the magnetic layer. The protection layer is formed on the predetermined area of the magnetic layer and protects the bar code. The pseudo bar code is formed on the magnetic layer and intermingled with the bar code. A card reader apparatus using this magnetic card is also disclosed.
