PURPOSE:To realize a sound signal recording device which is capable of reciprocation running by reducing a winding angle to a rotary magnetic head device of a tape, and also reducing a step difference of a tape running system. CONSTITUTION:A tape ruuning system is a double capstan driving form centering around a cylinder 9, and can make a tape run at a constant speed by a suitable tape tension. A tape step difference of the entry and the delivery of the cylinder due to winding spirally to the cylinder is corrected by inclining the cylinder, etc., and the entry and the delivery of a cassette become the same height. A spiral tape guide part 35 is provided on a lower cylinder 22, and a tape 4 is guided by a winding angle of 90 degrees or more. Rotary heads 24, 25, 26 and 27 are placed at intervals of 90 degrees, the rotary head 24 and 26 are placed so as to have a prescribed step difference in the direction of a revolving shaft, and the heads 24, 25 and 26, 27 are placed at the same height in the direction of the revolving shaft. Also, the head 24 and 26 have the same azimuth angle, and 25 and 27 have the same azimuth angle of an angle different from that of 24 and 26. |
