Optical reproducing/recording apparatus

An optical reproducing/recording apparatus comprising:

• a chassis comprising a first seat and three second seats;
• a turntable located on the chassis, for rotating an optical disc located thereon;
• an optical pickup head;
• and
• a guide device on which the optical pickup head moves, the guide device comprising a first and second beams, an end of the first beam being fixed on the first seat, the other end of the first beam and two ends of the second beam respectively being fixed on the second seats by an adjustable device;
• wherein the second seats have the same structure, each second seat has a groove and a corresponding groove surface configured for accommodating the beam, the groove surface of the groove has a recess defined at a bottom thereof, each adjustable device comprises an elastic element and an adjustable element, the elastic element is accommodated in the recess, and the adjustable element engages at a side of said groove and fixes the beam in the groove.
