    摘要: An apparatus reproduces signals which are recorded on a rotary medium having a main information signal recorded on a spiral main track, with first and second tracking control reference signals which are recorded on sub-tracks positioned between adjacent main tracks. A third tracking control reference signal is recorded on the main or sub-track, on each track turn, during an interval corresponding to the vertical synchronizing signal, within a vertical blanking period of the main information signal. The first and second reference signals are recorded within an interval excluding the interval corresponding to that of the vertical synchronizing signal. A kick pulse is generated for shifting the reproducing element to an adjacent track during a special reproduction mode so that the reproducing element is shifted at an interval other than the interval in which the reproducing element reproduces the vertical synchronizing signal.
