Pull-in Behavior Analysis in an Optical Disk Drive using Phase Plane and the Evaluations of Effecting Parameters for it

위상평면을 이용한 광디스크 트랙 끌어들임의 동적 해석 및 영향인자의 평가

In this paper, the track pull-in behavior analyses in an optical disk drive (ODD) using plane phase is treated and the parameters affecting it are discussed. Track pull-in is the track capture procedure to do track following control and it is key factor to increase data transfer rate. Simulation method, Runge-Kutta method to solve nonlinear equation, is used to evaluate the track pull-in conditions, and the real servo loop parameters are applied in this process to get the more real condition. Finally, the comments for the acquired results are discussed briefly.
