A Cost-Effective Scheme To Improve Radial Tracking Performance For Higher Speed Optical Disc Drives
نویسنده
چکیده
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%.

متن کاملTrack-following control using a disturbance observer with asymptotic disturbance rejection in high-speed optical disk drives
To obtain a good tracking performance in an optical disk drive servo system, it is essential to attenuate periodic disturbances caused by eccentric rotation of the disk. As an effective control scheme for enhancing disturbance attenuation performance, disturbance observers (DOBs) have been successfully applied to the track-following servo system of optical disk drives. In disk drive systems, th...
