オヘツドとを、 それぞれ配して成るＨアライメント記録装置。[Claim for Utility Model Registration] The amount of deviation in the track direction of each recording track shall be the average IH (H is the recording distance equivalent to one horizontal opening cycle) in standard recording mode, and 0.5H in long-time recording mode. In a two-head helical scan VTR, the first video head forms a first azimuth angle and performs recording in both recording modes, and the first video head forms a second azimuth angle and performs recording in both recording modes.
A second video head is arranged at a position preceding (or following) an angle corresponding to 0.5H from the 80° opposing position and records in the standard recording mode, and a second video head forming a second azimuth angle and 1.
．． This H-alignment recording device comprises a third video head with a narrow gap length and arranged to follow (or precede) by an angle equivalent to 5H and record in a long-time recording mode.
