In the disclosed method, pre-recorded bit markers are read from a magnetic medium as it is moved by hand at a highly variable speed past a magnetic read head. Pulses of a fixed frequency are counted between the reading of adjacent ones of the bit markers. Magnetic flux is written in one direction on the medium upon the reading of the bit markers; and magnetic flux is written in an opposite direction after a time period equal to a fraction of the number of pulses counted between bit markers times the reciprocal of the fixed frequency. Also disclosed is apparatus for performing the steps of the disclosed method.
