光電產業一直是政府積極輔導與推動的重點產業，不論是在光顯示、光儲存光通訊、光輸入、光輸出產業等，歷年來都有不錯的成績。其中尤其是光顯示與光儲存更是占整體產業的大宗。歷年來在掃描器、光碟機、光碟片等多項產品，都曾有位居世界霸主的地位。 自從光碟片問世以來，光碟已經扮演現代科技的重要角色，它既方便攜帶還有儲存容量也大，體積、面積也小了許多，非常符合現代要求如此高效率的時代，而光碟的用途也分成很多類，例如儲存影片、音樂、軟體等等用途，由於光碟的問世，也使得早期使用的磁片、錄音帶、錄影帶等等這些東西，都逐漸被光碟給取代。而光碟從只能儲存聲音的功能，發展到可以儲存影片、軟體等。在這其中，台灣廠商以優異的製造能力與快速擴展產能的策略，建立起光碟片製造王國，總產量佔世界第一，前幾大光碟廠皆為台灣廠商。然而，台灣光碟廠商雖然隨著市場需求而持續成長，但卻始終陷在供過於求的產業困境中，價格快速下跌，加上高額權利金負擔，讓台灣光碟廠陷入經營的窘境。本研究主要是針對紀錄型光碟片產業，收集相關產業資訊，並根據文獻探討擬定研究架構作為產業分析之基本架構；探討過去產業快速成功但卻又深陷供過於求的泥淖的原因，在競爭優勢分析上運用波特競爭理論、五力分析與鑽石理論，並以個案公司為例，瞭解台灣光碟片產業之競爭優勢情形，對產業未來發展提出策略建議。 / Optoelectronics industry has been the focus and promoted by the government. The optical display, optical storage, optical communication, optical input, and optical output industries, have gained good performance in the past years. Especially the scanners, optical disc drives and optical disc media had been the dominant roles in the world。 Since the introduction of the optical disc, it has played an important role in modern high technology. It is convenient to carry over, its large capacity, and the compact size, all meet the requirements of high efficiency. The disc can be used for various purposes of video, music, and data storage and it quickly replaced the floppy discs, audio/video tapes. Taiwan's manufacturers used the strategy to build up the huge capacity rapidly with excellent production capability. The total output has been world number one. However, the market demand continues to grow, but it has been always stuck in oversupply. The rapid declining product prices and the high loyalty burden make the manufacturers in awkward situations. The purpose of this thesis is to focus on analyzing why it succeeded before and why it became oversupply by collecting industry information, literatures, and documents. Based on Porter’s competition theory, theory of five forces analysis and diamond model, and we use A Company as an example to figure out the possible strategies of this industry.

For the last ten years, DVD-R media have played an important role in the storage of large amounts of digital data throughout the world. During this time it was assumed that the DVD-R was as long-lasting and stable as its predecessor, the CD-R. Several reports have surfaced over the last few years questioning the DVD-R's ability to maintain many of its claims regarding archival quality life spans. These reports have shown a wide range of longevity between the different brands. While some DVD-Rs may last a while, others may result in an early and unexpected failure. Compounding this problem is the lack of information available for consumers to know the quality of the media they own. While the industry works on devising a standard for labeling the quality of future media, it is currently up to the consumer to pay close attention to their own DVD-R archives and work diligently to prevent data loss. This research shows that through accelerated aging and the use of logistic regression analysis on data collected through periodic monitoring of disc read-back errors it is possible to accurately predict unrecoverable failures in the test discs. This study analyzed various measurements of PIE errors, PIE8 Sum errors, POF errors and jitter data from three areas of the disc: the whole disc, the region of the disc where it first failed as well as the last half of the disc. From this data five unique predictive equations were produced, each with the ability to predict disc failure. In conclusion, the relative value of these equations for end-of-life predictions is discussed.
