Abstract
In a two-head helical scan video tape recorder, a pair of rotary erase heads are provided, and in order to avoid undesirable erasure by fringe flux, each rotary erase head integrally formed with one of two video recording heads and is positioned on a rotary member so that the scanning position thereof is always displaced from the scanning position of the associated video recording head by at least one video track interval in the scanning direction of the heads, in case of guardbandless azimuth recording.
