Optical disk drive (ODD) technology has been rapidly improved to treat the gradually increasing data storage and data transfer rate. The rotational velocity of the disk must be increased to deal with huge data. However the increased rotational velocity can inherently cause unwanted phenomena such as noise and vibration. The major noise sources of the ODD system are mechanical vibration which generated inside ODD and turbulent aerodynamic noise which generated by the viscous flow rotation. In this study, practical experimental tests of driving noise for various optical disk drives have been performed using 1/2” microphone noise measurement system. Sound insulation case with absorbing materials for the present experimental tests is designed and constructed in order to minimize the effects of disturbance. Several commercial ODD models by different manufacturers are practically considered in the present experiments and compared for realistic driving conditions. It is shown that sound noise level, average data transfer rate and operating RPM seems to be somewhat different for the ODD models with same proposed speed by different manufacturers. Moreover, driving sound noise level can be largely affected by both tray shape and driving speed even for the same apparent data transfer rate.
