ABSTRACT:
In a recording/reproducing apparatus having rotary heads, heads A, C, E and G having a first azimuth, and heads B, D, F and H having a second azimuth are alternately arranged, and heads A' and E' having a second azimuth are disposed adjacent to the heads A and E', respectively. The use of the heads A', C, E' and G permits recording and reproducing at 1/2 speed with the same track pitch. The positions of the heads A and E are deviated by predetermined amounts from the equal interval positions on the periphery of a rotating drum so that recording and reproducing can be performed with the same track pitch at least at 1/4 speed.
