TITLE OF THE INVENTION: Rotary Head Assembly for Magnetic Recording and Reproducing Device ABSTRACT OF THE DISCLOSURE: In a rotary head assembly for a magnetic recording and reproducing device of the type in which rotary head member is engaged through a hydraulic bearing with a shaft whose one end is securely fixed to a base and the other end is free, the position of a thrust supporting member formed at the free end of the shaft is suitably selected so as to minimize the adverse effects caused by the thermal expansions of the component parts whereby the variation in relative position between the head and tape due to the temperature variation can be minimized and the high radial rigidity can be attained.
