Abstract
PURPOSE:To eliminate both the head coil and the transformer component at the rotating side, by transmitting the change of magnetic flux of the head to the transformer component at the fixed side and then extracting the change of magnetic flux passing through the magnetic path in the form of the electric change. CONSTITUTION:The heads 12a and 12b are fixed onto the cylinder 1 and then rotate along with the shaft 11 with a minute gap kept to the upper surface of the transformer component 7 of the fixed side. For the reproduction of the tape received the magnetic recording, the heads 12a 12b are shifted toward the arrow A to the tape, and thus magnetic flux is caused within the head as shown by the broken line. This magnetic flux passes directly through the inside of the component 7 to give the electric change to the transformer coils 10a and 10b of the fixed side. And this electric change is extracted in the form of the reproduced electric output. As a result, the transformer component at the rotating side can be eliminated, thus simplifying the assembling work as well as reducing the transmission loss greatly.
