Abstract
An apparatus for reproducing a video signal recorded in skewed parallel tracks on a magnetic tape compensates both for cross-track and along-track errors during reproduction at a tape speed different from the tape speed employed during recording by affixing reproducing heads to bi-morph leaves which are skewed with respect to the direction of rotation of a rotating drum to which they are attached. The skew has components in the along-track direction and the across-track direction such that unidirectional motions of the bi-morph leaves simultaneously correct for cross-track and along-track errors.
