A system for cooling a semiconductor light source bar during burn-in testing includes a fixture for holding the semiconductor light source bar, and the fixture including a housing having a water inlet channel and a water outlet channel communicated with the water inlet channel; a first water tank with coolant connected with the water inlet channel; a second water tank connected with the water outlet channel; and a pumping device at least connected with the water outlet channel for pumping the coolant from the first water tank to the second water tank, thereby rushing a bottom of the semiconductor light source bar to lower the temperature thereof. The system can disperse the local heat generated during burn-in testing and uniform the local temperature of the semiconductor light source bar, thereby maintaining a proper temperature during burn-in testing and improving the heat stability of the heat assist magnetic recording head.
