Abstract
The disclosed information signal recording and/or reproducing apparatus records or reproduces an information signal by shifting two electric-to-mechanical conversion elements which respectively have heads mounted thereon. Each electric-to-mechanical conversion element has a residual displacement characteristic. The shift direction of one conversion element is arranged to be the same as that of the other immediately before switchover from a first mode to a second mode. In the first mode, the difference between voltages impressed on the two elements is relatively large, and, in the second mode, the difference between voltages impressed on the two elements is relatively small.
