Abstract

PURPOSE:To obtain excellent slow-motion reproduced pictures by preventing the lowering of a reproduction output for slow-motion reproduction, by selecting a greater output between two adjacent magnetic heads differing in azimuth angle and by outputting by switching head outputs. CONSTITUTION:On a guide ring 1, the 1st and 2nd magnetic heads A and B differing in azimuth angle by about 180 deg. mutually are arranged and in the same rotating plane with the heads A and B, the 3rd and 4th magnetic heads A' and B' are provided adjascent to the heads A and B. When the distance between horizontal synchronizing signals recorded on a tape 2 is H, the distance (l) between the heads A ane B' and the distance (l) between the heads B and A' on the external circumference of the rotating plane of those magnetic heads are nH (n; integer). For slow-motion picture reproduction at the running speed of the tape 2 one-(n)-th that in recording, a greater output between those of the adjacent heads A' and B' is selected to change over the head outputs, thereby outputting excellent slow-motion reproduced pictures.
