  •   本論文探討光碟機轉速規劃和碟片偏擺效應的伺服系統補償。在光碟機的設計中有必要提升資料傳輸率以快速讀取碟片的資料。在不更動主軸馬達的情況下,可以利用轉速規劃的方式來提升資料傳輸率。論文中採用最佳化法則來設計轉速規劃曲線以因應不同運作模式及電路限制。本論文的另一重點為碟片偏擺之控制,碟片偏擺是高速光碟機之一項重要誤差源。論文中藉由模式分析探討碟片偏擺效應,並採用多種控制法則,分別評估偏擺控制之效益。這些法則的發展均藉由一市售光碟機予以實作、實現、與評估。

      In this dissertation, the focuses are on the speed profile design using optimization methods and compensator design against disc run-out phenomena in optical disc systems. One issue in optical disc system servo design is the increase of data transfer rate for multi-media application. The increase of data transfer rate, however, can only be achieved by considering the issue of spindle motor characteristic, decoding electronics, and access time requirement at the same time. In this dissertation, a hybrid CAV-CLV profile is obtained that satisfies the given constraints and maximizes the average bit rate in disc tracking. Disc run-out effect is the major error in low frequency band of servo control system in optical disc drives. The servo control techniques can be explored to compensate for the disc run-out, and improve the readability. To this end, a mathematical method is utilized to model the disc run-out mechanism, and characterize the run-out behavior. Five control methods are then applied to the disc servo system to reduce and/or eliminate the error due to run-out.

      The methods are implemented and verified using retail CD/DVD-ROM drives. The design/analysis results are closely matched with the experimental data.
