ータリトランス。 In order to transmit signals between the magnetic head mounted on the rotating body and the magnetic recording/reproducing circuit, a rotary transformer on the rotating side is fixedly installed on the rotating body, and a lower cylinder rotatably supports the rotating body. In a rotary transformer of a magnetic recording and reproducing device in which a fixed side rotary transformer and a fixed side rotary transformer are disposed concentrically facing each other, an air flow is generated on the outer surface of the rotating side rotary transformer when the rotating body rotates. A rotary transformer characterized by forming uneven parts.
