ABSTRACT:
A recording and reproducing apparatus includes a rotatable rotating assembly and a fixed assembly disposed opposite thereto. The apparatus also includes a plurality of recording and reproducing heads and an erasing head mounted on the rotating assembly and first and second rotary transformers, having primary windings mounted on the rotating assembly and secondary windings mounted on the fixed assembly. A control signal generator is mounted on the rotating assembly and receives signals via the primary winding of the second rotary transformer. A first signal processor is mounted on the rotating assembly and connects the plural recording and reproducing heads to the primary winding of the first rotary transformer and a switch connects the erasing head with primary winding of the second rotary transformer. A recording and reproducing processor is connected the secondary winding of the first rotary transformer while a modulation signal generator is connected to the second winding of the second rotary transformer. A power supply is mounted on the rotating assembly is connected to the primary winding of the second rotary transformer. The apparatus enables M transformers to power N heads, where M and N are integers and M is less than N, thereby enabling the use of plural heads through one rotary transformer.
