Abstract
In a method for recording a new coded message in place of an old coded message recorded on a magnetic stripe carried by a support document by manual displacement of said document, the message being divided into a first part and a second part separated by a gap, the clock signal used to write the first part of the new message is a clock signal obtained by reading the second part of the old message. The clock signal used to write the second part of the new message is a clock signal obtained by reading the first part of the new message, newly written. The system for implementing this method comprises a write head between two synchronization heads and an electronic circuit which produces from the signals from the two synchronization heads a clock signal slaved to the speed of displacement of the support document. This clock signal is sent to a write signal generator connected to the write head. The write signal generator also receives the data to be recorded.
