System for the recording and play-back of video signals

摘要

A system is provided for increasing the recording/play-back time for video tape devices. A tape is utilized on which signals are recorded in one direction for one half the tape width and in the opposite direction for the other half of the tape width. The tape drive mechanism automatically reverses at the end of feed in each direction and when the tape feed direction changes the relative vertical position of the tape head (or heads) with respect to the tape also changes.
