Abstract
An apparatus for reproducing a signal from a rotary recording medium comprises a rotary structure adapted to carry the rotary recording medium thereon and to rotate, the rotary structure being shaped to form spaces between itself and the rotary recording medium, an air suction pump, and a structure formed at the center of the rotary structure or in the vicinity thereof thereby to provide communication between the spaces and the air suction pump. The rotary recording medium is drawn into intimate contact with the rotary structure so as to eliminate any warp in the rotary recording medium and cause the rotary recording medium to rotate together with the rotary structure.
