TRACKING SERVOCONTROL CIRCUITS FOR USE IN AN OPTICAL REPRODUCING APPARATUS ABSTRACT OF THE DISCLOSURE A tracking servocontrol circuit for use in an optical reproducing apparatus comprises signal generating means for generating a tracking error signal representing a tracking error in respect of a light beam scanning the record track on a record medium from which a reproduced information signal is obtained, a servocontrol amplifier provided to be supplied with the tracking error signal for producing a drive signal in response to the tracking error signal and supplying with the same to a driving device for tracking servocontrol, a defect detecting means for detecting a variation in the reproduced information signal resulting from a defect on the recorded surface of the record medium, and control means operative to reduce the gain of the servocontrol amplifier or limit the amplitude of relatively high frequency components in the tracking error signal supplied to the servocontrol amplifier when a predetermined detection output is obtained from the defect detecting means, so as to prevent the drive signal supplied to the driving device being harmfully affacted with the defect on the recorded surface of the record medium.
