Rotary hetsudo type dejitaruo - deio reproducing arrangement

PURPOSE:To feed no wrong track slippage amount to a capstan servo by performing the sampling hold of a pilot signal component after the fixed term while an actual sink signal exists, after detection of a pilot signal. CONSTITUTION:The level of the crosstalk of the pilot signal of the adjacent track of one part is subjected to a sample hold after prescribed fixed time according to the recording pattern in compliance with the detection of a pilot signal, and the signal expressing the track slippage amount is formed with the level being held after further fixed time thereafter and the level of the crosstalk of the pilot signal of the adjacent track of the other part to perform the control of a capstan servo. Due to the crosstalk of the adjacent track of one part being not made to subject to a sample hold immediately according to the detection of the sink signal only,a correct tracking can be taken without any malfunction even if an alias sink signal due to an override exists before the actual sink signal.
