1. The magnetic card recording/reproducing apparatus for recording/reproducing magnetic information in a magnetic card, comprising: a coercive force identifier for identifying the coercive force of the magnetic card before magnetic information is recorded in the magnetic card; and an exciting current supplier for selecting one of plural predetermined exciting current values as exciting current to be supplied to a recording magnetic head for recording the magnetic information in the magnetic card on the basis of the identification result of said coercive force identifier so that the magnetic information will be recorded in the magnetic card with the exciting current thus selected by a reproducing magnetic head for reproducing the magnetic information from the magnetic card.
