Abstract

Optical disk driver is being used in many electronic products besides computer. In particular, the demands are recently increased as an optical disk player in the mobile products such as camcorder or in the home theater appliances, or etc. However, under these circumstances, the disturbance inputs to the optical disk player increase gradually. In this paper, for reducing the possibility of malfunction of the optical disk player, we propose the method of detecting and controling the non-periodic external shock of the disturbances. Also, we execute some simulations and actual experiments and discuss the results.
