Abstract
Apparatus for simultaneously reproducing video signals having block synchronization signals and that have been recorded in successive, parallel channel tracks extending obliquely on a magnetic tape, with adjacent ones of the tracks having the video signals recorded therein with different azimuth angles, the apparatus including two magnetic heads movable in a direction along the channel tracks for reproducing the signals recorded therein; a phase detecting circuit for detecting a phase error between the block synchronization signals reproduced from adjacent ones of the tracks by the two magnetic heads; and a control circuit for controlling the relative positions between the tracks and the magnetic heads in response to the detected phase error so that the two magnetic heads accurately scan respective ones of the tracks.
