PURPOSE:To suppress a crosstalk, to miniaturize the titled head, and also, to improve the noise resistance by providing plural magnetic heads, a reproducing circuit, a selecting and switching circuit of the magnetic head, an inputting/ outputting circuit to the fixed side, and a solar battery on a rotary drum. CONSTITUTION:A rotary head 1 has a rotary drum 2 and a fixed drum 3. To a prescribed position of the drum 2, magnetic heads 6a-6d are installed, and in the inside, a reproducing circuit 10 and a selecting and switching circuit 11 are installed, and also, to the upper face, a solar battery 14 is attached. A lamp 15 for irradiating the battery 14 by light and a power source circuit 16 of the lamp 15 are provided on the fixed side. Outputs of the heads 6a-6d are sent out to the circuit 10, and a reproducing signal is inputted to a signal processing circuit 13 through coils 7a, 8a of a rotary transformer 9. A selecting and switching control signal outputted from a switching control circuit 12 of the fixed side is sent out to the circuit 11 through the transformer 9, and one of the heads 6a-6d is selected. In such a way, a crosstalk can be suppressed, the titled head can be miniaturized, and also, the noise resistance can be improved.
