Abstract

The periodic disturbances caused by the inherent eccentricity and unbalancing in compact disc systems is one of the prominent radial-tracking problems in high-speed and high-density optical storage systems. To compensate these periodic disturbances, an adaptive feedforward compensation technique is presented and investigated with the aim to have cost-effective optical disc drive manufacturing. Computer simulations and experimental evaluation on a high speed CD-ROM product show that the proposed adaptive feedforward compensator is very effective and provides a way to significantly improve the radial tracking performance by reducing the radial error by 85%.
