OPTICAL DISK DRIVE OF NOISE ATTENUATING CHARACTERISTIC AND NOISE ATTENUATING APPARATUS

摘要

This invention relates to an optical disc drive having a noise attenuation characteristic , and the disc tray for mounting a disc ; And the disk drive section for driving the disc to be mounted on the disc tray ; And the optical pick-up module for recording / reproducing data on the disk ; The disc tray , the disc drive unit , in the optical disk drive comprising a main frame which is an integrated optical pick-up module , the part that separates the interior space and the outer space of the optical disc drive , noise having openings of differing width in the longitudinal direction characterized in that it comprises a reduction . ; by the noise reduction section like this, the optical disc drive noise can be significantly reduced , which occurs when the drive .
