<p>A plurality of different pilot signal components are selectively superposed on an information signal, and mark signals which can indicate the types of pilot signals to be superposed are recorded, together with the information signal, on tracks on a recording medium, on which the pilot signals associated with the mark signals are recorded. The types of pilot signals can be quickly detected in a reproduction mode, and a satisfactory tracking control state is quickly achieved by modifying the tracking control signal. When the pilot signal components are superposed on the information signal on every other ones of a large number of parallel tracks, tracking error signals can be formed from reproduction signals from first and second heads for tracing neighboring tracks, and tracking control is executed using these tracking error signals. <IMAGE></p> |
