ABSTRACT:
A tracking control circuit of a rotary head type magnetic recording and reproducing apparatus. The tracking control circuit generates sampling pulses of first and second pilot signals for tracking based on a synchronization signal for tracking on a recording track, detects an envelope signal from the reproduction signal reproduced by the magnetic heads which is amplified with a predetermined gain, detects tracking error data from first and second pilot data obtained by sampling the envelope signal with the sampling pulses, detects reproduction level error data, controls the feeding speed of the magnetic tape based on the tracking error data, and controls the amplifying gain of the reproduction signal based on the reproduction level error data. As a result, deviations of reproduction levels of the magnetic heads are effectively corrected, and tracking control of the magnetic heads on the recording tracks is extremely precise.
