Abstract

PURPOSE:To prevent the generation of noise disturbance or a malfunction by providing a rotary transformer having a pair of power transmitting auxiliary windings other than a signal transmitting main winding, and providing a signal amplifier inside a rotor. CONSTITUTION:An electric signal induced by a magnetic head element 4 is amplified into a large signal by the signal amplifier 12 arranged in a very short distance, and the output is supplied to the signal transmitting main winding 7a or 8a, and after being induced in the main winding 7b or 8b through the rotary transformer, is transmitted to a following circuit from a signal drawing lead 3. On the other hand, the driving power source of the signal amplifier 12 is supplied to a rectifier 13 as an AC power through power transmitting auxiliary windings 11a, 11b, and after being rectified by the rectifier 13 into a DC current, is supplied to the signal amplifier 12. Thus, the ratio of the signal versus the noise can be taken to be large, and the noise disturbance or the malfunction can be prevented.
