Paper Abstract

The light intensity distribution at the pupil of the objective lens, the numerical aperture of the objective lens, the retardation inside optical pickup heads (PUHs) and the wavefront aberration of the lase beam radiated from the objective lens are dominant factors, which affect the drive to drive variation in DVD (Digital Versatile Disc) signal quality testing. The impact of each factor on the jitter measurement is experimentally analyzed. According to these analyses, a tester PUH was developed. The consistency comparison of jitter measurement between the consumer players and DVD testers are demonstrated.
