An Actuator Laser of Optical Disk Drive High-Frequency Electromagnetic Vibrations Characteristic Analysis
The actuator has widely used in CD and DVD system it have more application foreground in the future, but nonlinearity and creep exist in the actuator, which limit actuator application in high capacity, high redundancy, high transfer rate and short access time system. In this paper, we give a detail introduction on the actuator laser of optical disk high-frequency electromagnetic vibrations characteristic.
