NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick- up block. Therefore, when checking the laser diode emission, observe from more than 3

12、0 cm away from the objective lens. The emission check enables continuous checking of the S curve. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times. TABLE OF CONTENTS 1. SERVICE NOTE 3 2.
