Abstract
A system for automatically erasing a pair of tracks whenever a designated track to be erased belongs to a pair of tracks representing a frame picture. In the system, detecting means detects ID codes indicating field/frame recording mode of a recorded track and feeds a detected signal to a controller, then the controller takes an appropriate action to erase the pair of frame recorded tracks by timely activating head accessing means and an erasing signal generator based on the ID codes, whenever the tracks correspond to a frame picture.
