ABSTRACT:
An auto tracking apparatus is arranged to divide a tracing time period of one field of a frame into a plurality of time domains and to sample and hold the envelope detection output signal of a reproduced high frequency signal at every time domain. This sample-and-hold operation is successively made for the following frame and each of the sampled values is compared with the previously value sampled at the corresponding time domain. In accordance with the results of the comparison the displacement of the reproducing head is controlled at every sampling point so that a reproducing head can accurately scan the track along the center line thereof.
