Abstract

PURPOSE: To make it possible to use a card in a magnetic card recording and reproducing apparatus, into which the card may be inserted in either direction, by forming a magnetic recording band at the center line of the magnetic card and by specifying the arrangement of the magnetic recording track.
CONSTITUTION: A magnetic recording band 2 is formed at the center line of a magnetic card 1, and magnetically recorded tracks are arranged such that first and forth tracks 4 and 7 and second and third tracks 5 and 6 are symmetri with respect to the center line of the card. On the other hand, a magnetic card recording and reproducing apparatus 8 is equipped with a magnetic head assembly 9, which is operative to read out the information of the recording band 2 when the card 1 is inserted, such that the track 4 corresponds to the first head 10 of the head assembly 9 while effecting correspondes between the tracks and the heads, respectively. In case the card 1 is inserted backward, therefore, the reproducing apparatus 8 backwardly reads out the information, which is recorded in the card 1, and changes it into the information which is read out in the forward direction.
