PURPOSE: To provide a magnetic card increased in the storage capacity of magnetic data and its processor by connecting magnetic tracks and using plural data as an combined data.

CONSTITUTION: The magnetic card 11 provided with a magnetic stripe 12 capable of writing/reading out magnetic data in/from the card surface is characterized by setting up plural magnetic tracks 13a to 13e parallel with a data processing direction on the stripe 12, connecting respective tracks 13a to 13e as one track so as to continuously connect data and successively record them. On the other hand, a magnetic card processor is provided with a magnetic data processing means for continuously connecting plural magnetic tracks 13a to 13e formed in parallel with the data processing direction of the magnetic stripe 12 and processing magnetic data.
