<p>A temperature gain compensation system for disk label laser etching process contains a servo device, a Digital Signal Processor (DSP), a driver IC, and a temperature compensator. A temperature sensor in the servo device transmits a temperature signal to the temperature compensator. Then, the temperature compensator obtains a temperature difference and calculates a corresponding feedback control signal. The DSP and the driver IC process the feedback control signal to adjust the servo device.
