“…The resonance modes can be divided into the in-plane and out-of-plane modes as shown in Fig. 1 [6,7]. The in-plane modes are the pre-dominant modes as they move the head in the radial direction of the track, this translates into direct off-track motion generating a position error in the servo.…”

“…The recording head reads the servo data pre-written on the track to provide feedback to the servo for positioning; thus, forming a closed-loop servo system. Depending on the frequency location and amplitude, the structural resonance of the actuator impacts the performance of the servo [1][2][3][4][5][6][7]. The resonance modes can be divided into the in-plane and out-of-plane modes as shown in Fig.…”

The purpose of this paper is to improve the NVD optical disk driver performance in combined sound system. Based on the optical valley of China-Wuhan R&D (research and development) red HD-NVD mecha system application, structural dynamic characteristics of the optical disk driver main parts and vibration isolation system can be analyzed by the multi-physical analysis software, ALGOR. Obtain the various modal parameters of vibration isolation system provides a solution of the unstable problem of the optical disk driver working performance which due to the low frequency vibration audio system. It is theoretically showed that the secondary vibration isolation system is feasible and laid the foundation for the optimization design of vibration isolation system.
