초록정보

A multi-beam optical disc drive is a method to improve the data transfer rate for the optical disc systems by parallel recording and reading on neighboring multi-tracks. In this paper, the beam rotating actuator, which is necessary for the multi-beam optical disc drive to form beam spots on multi-tracks simultaneously, has been developed. The Voice Coil Motor is used as a drive mechanism for high resolution and small size of the actuator. And rotating guide based on link structure is designed for frictionless and axisless rotation of rotating part including dove prism. The characteristics of the actuator are experimented by laser and a dynamic analyzer. It shows that the actuator has good linearity, rotating range ±0.34˚ and natural frequency 113.9Hz and rotates in axis of geometric center of dove prism. Also PID control using sine inputs shows that rotating resolution of multi-beam is below 0.029˚. Therefore the actuator can be applied in a multi-beam optical disc system.
