Abstract
The present invention provides apparatus for calculating the skew distortion introduced in each channel of a multi-channel longitudinal recorder when recorded information signals in at least two channels contain a detectable characteristic. In accordance with the invention, a timing signal is recorded containing certain information that is used, upon playback, to produce a reference marker which is compared with the detectable characteristics of recorded information signals to produce a measure of skew distortion.
