Abstract
An information signal comprised of a video component and a tracking information component which has been recorded in parallel oblique tracks on a record medium is reproduced by plural transducers which scan successive tracks. The tracking information component is separated from the reproduced information signal to derive error detection signals representing scanning errors of the transducers. Plural ones of the error detection signals are averaged to produce tracking control signals.
