发明名称 Variable speed recording and/or reproducing apparatus including a plurality of rotary heads arranged with head gaps having particular azimuth angles
摘要 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 +E,fra 1/2+EE 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 +E,fra 1/4+EE speed.
