A Colpitts type oscillator circuit for mitigating the effects of undesired oscillator ringing when write pulses are supplied, such as those encountered in compact disc, laser disc, and magneto-optical players or recording devices. Circuit elements are provided for mitigating the effects of oscillator ringing including replacement of an inductor with a suitable resistive load and an oscillator supply voltage maintained above a predetermined minimum voltage which is a function of the specific values of the related circuit elements. An improved optical disc system also includes the present Colpitts type oscillator in combination with an optical assembly, a laser light source, an objective lens subassembly, an objective lens, an actuator assembly, a photodetector, first and second servomotors, a source of write pulses, a first electronic circuit for controlling the servomotors, a motor for moving a respective disc, a second electronic circuit for decoding, a third electronic circuit for enabling the laser light source, a voltage supply for the oscillator, a data receiver, a data encoder, a magnetic field generator, a cartridge loading assembly for removably positioning the respective disc, and a servo error circuit for determining when light returning from the disc exceeds a predetermined value.
