The stabilizer comprises a solid disc having a center opening and having an axial length which is less than the length of the centering spindle on the turntable, and an upper and a lower plate which cover the upside and the downside of the center opening formed in the disc to define an air tight air chamber therebetween. Annular elastic seals are mounted around the outer periphery, the inner periphery and on the upper surface of the disc to define an air space between the record disc, the upper surface of the disc and the elastic seals. The air space may communicate with the air chamber, to which a negative pressure may be applied to hold the record disc by attraction.
