Abstract

PURPOSE: To use the pilot signals for each track during the recording operation and the pilot signals, which are reproduced from a recording head, during the reproducing operation thereby to accomplish the auto-tracking operation by using wide and narrow heads for the recording and reproducing operations, respectively.
CONSTITUTION: Wide and narrow heads H1 and H2 are fixed at a preset spacing to a rotary cylinder. During the recording operation, respective tracks are recorded adjacent to each other by the head H1, and pilot signals are recorded for each track. During the reproduction, on the other hand, video signals are reproduced by the head H2, and the head H1 scanns, while riding over adjacent tracks, when the head H2 scanns the center of the recorded track. The output of the two heads H1 and H2 are fed to terminals 14 and 18, respectively, so that their levels are compared. If there is any difference in the output levels, the relative positions of the head and the recorded track are shifted so that the head H2 may scan substantially the center of the recorded track.
