For recording digital data on a magnetic recording medium, binary data signals and magnetic bias signals having a constant repetition rate are synchronized in terms of phase, are overlaid, and are subsequently supplied to a magnetic head. The phase-oriented synchronization thus occurs since the chronological spacings between two successive signal edges of the magnetic bias signals between two successive signal edges of the data signals given a plurality of magnetic bias signals are modified such that the directions of the signal edges of the data signals coincide with the directions of the corresponding signal edges of the magnetic bias signals. The sums of the components having a first binary value and a second binary value of the magnetic bias signals are identical. Preferably, the distances between two successive signal edges of each of two magnetic bias signals are respectively shortened by half between two edges of a data signal.
