PURPOSE:To control assuredly tracking of a rotary head by recording plural positioning signals and tracking pilot signals, the detecting the pilot signal by using the reproduction output of the positioning signal as the reference. CONSTITUTION:The tracking pilot signal and the erasion signal are recorded to a magnetic tape, and the erasion signal is used as a positioning signal. A head 1B reproduces a pilot signal PA2 of a track 5B2 and pilot signals PB2 and PB1 of adjacent tracks 5A2 and 5A1 at an area AT1. A sampling pulse corresponding to each pilot signal is formed according to erasion signals (EA2, EA4 and EA6 during a period tB). Then the peak is held for the crosstalk of the pilot signals of tracks 5A2 and 5A1. The difference of tracking signals corresponding to each crosstalk between pilot signals PB2 and PB1, PB4 and PB3 and PB6 and PB5 is obtained as a tracking control signal.
