Relationship of Magnetic Card Signals

Relationship of Magnetic Card Signals

Magneticcards have three separate magnetic tracks. Each individual track has three separate signals: the Card Loading Signal (CLS), the Read Clock Pulse (RCP), and the Read Data Pulse (RDP). The Card Loading Signal indicates that the magnetic card being written to has been pulled past the read head. The CLS signal continues to be active during the data read and clock signal until the magnetic card is removed. The RCP clock signal and the RDP data signal are separated by an F2F demodulator.
