Abstract

PURPOSE: To improve unclearness of a reproduced sound in a low frequency range and indistinction of sound image localization by arranging a stabilizer with fixed operation characteristics on a turn table.
CONSTITUTION: With record sheet 2 interposed, record 3 is mounted on turn table 1 of moment of inertia Ja, and at the outer circumference of record 3, stabilizer 4 with moment of inertia Jb is arranged. Further, DD motor 5 is brought under speed control by a speed proportional control loop of gain G2 consisting of speed detector 6, speed voltage converter 7, comparator 8, and amplifier 9 and a speed integral control loop of gain G1 consisting of phase difference detection circuit 11 and mixer 12. Then, stabilizer 4 operates to set natural vibration frequency (G1/Ja+Jb)1/2/2π of the unit below a flutter frequency at which a detection limit is lowest.
