とを特徴とするビデオテープレコーダ。[Claims for Utility Model Registration] (1) In a video tape recorder that records video signals on a magnetic tape by a helical scan method using a rotary head cylinder having at least one pair of recording video heads, the rotary head cylinder includes: , a playback head mounted with a step in the axial direction of the rotary head cylinder so that the phase is advanced by a predetermined angle in the rotational direction with respect to each of the recording video heads and traces the same video signal track. each equipped with a head device,
A video tape recorder characterized in that a new video signal is recorded after the video signal previously recorded on the magnetic tape is played back by the playback head device. (2) In the description of claim 1 of the utility model registration claim, the playback head device includes a playback head and an erasing head, and the playback head rotates in a predetermined direction with respect to each of the recording video heads. 1. A video tape recorder characterized in that the erasing head is positioned so that the phase is fastest in terms of angle and traces on the same video signal track, and then the erasing head is positioned next.
