ABSTRACT:
A rotary scanning device is proposed with a rotary body carrying at its periphery a plurality of magnetic recording heads which can be driven by associated recording amplifiers. The individual recording amplifiers are accommodated on circuit boards which are mounted in a paddle-wheel configuration between two annular conductor boards by means of holders. The two annular conductor boards are rotationally locked to the rotary body. The circuit boards have a forward inclination in the direction of rotation of the rotary body.
