Abstract

The rotational speed of optical disks must be above 15,000 rpm owing to the required high data-transfer rates. At these speeds, the airflow between the rotating disk and a rigid wall is important when identifying the dynamic characteristics of the disk in a slim optical disk drive. This airflow is simulated using a numerical model and examined by a closed-form modal analysis. The calculated dynamic characteristics of the rotating disk can be used to predict the nonrepeatable runout for the servo controller design.
