Abstract
PURPOSE: To conduct a still reproduction without causing a skew distortion, by providing one head and another separated by the angle corresponding to the shift of the position of a horizontal synchronizing signal to one head fitted in the distance of 180° on the drum.
CONSTITUTION: The heads 2A and 2B different in azimuth angle are fitted in the distance of 180° on the rotary drum 150, and the tape is wound over the angle range of 180° or more with a slope to the rotary surface of the drum 150. On the drum 150, the heads 2A and 3A are placed to the position apart from the angle corresponding to the position shift of a horizontal synchronizing signal to the head 2A. Further, at still and double speed reproduction, the head 3A moves to the synthesized direction of raial and axial directions within a given range to the drum 150 and the output of the heads 2A and 3A is picked up as a reproduction signal. Thus, still and double speed reproduction can be made without a skew distortion.
