ABSTRACT:
A system to improve image quality during shuttling of a video tape in a record and playback machine of the type in which each image field is recorded on one or more tracks on video tape. The system includes an offset signal source coupled to a displaceable mechanism during shuttling to provide relative displacement between a reproduce transducer and a video tape to cause the transducer to cross tracks of recorded information irregularly, thereby providing frequent updating of substantially all regions of an image field by information stored on the tape.
