Because of its inherent Even as DVD technology attracts require flexible, cost-effective storage flexibility and affordability, considerable attention, venerable CD capabilities. CD-R, with its advantages technology is not only holding its own, in media compatibility, longevity, and optical storage technology but recordable versions are making portability, meets these needs. continues to grow at a rapid substantial gains. In particular, CD-R Recordable CDs are now being used pace. and CD-RW media will continue to be to receive, store, and disseminate large leading data storage solutions for the quantities of digital, analog, audio, next five to 10 years, according to video, and graphic data. The rapid This evolving technology Raymond C.

Freeman says that the 1.4 software. billion CD-R discs sold worldwide in A steady drop in price is also fueling only capabilities (CD-ROM), 1999 is just a beginning, predicting continued growth in the recordable CD to CD-Recordable (CD-R) that 3.3 billion units will be sold in marketplace.

In addition, demand for CD-RW $1 each — that’s fifteen-hundredths of drives is growing sharply according to a cent per megabyte, far less than other ReWritable (CD-RW) format.

However, there is a great deal of overlap between these two subject areas. In particular, multilevel recording is enabled by signal processing technology improvements in the writing and reading of an optical data storage system. Thus, it seemed logical to combine the subgroups that cover these areas. On the other hand, the technology of multilevel recording has grown substantially in its own right since the last roadmap was published in 2000. In this section, we first introduce the current state of signal processing technology. Within the discussion of the current state of the technology, we have a separate subsection that introduces the basics of multilevel recording and reviews three examples of multilevel systems. We then focus on signal processing areas that, in the future, are likely to become important for optical data storage. And finally, since signal processing in general is mostly an enabling technology and would be difficult to “roadmap”, we present a roadmap for products using multilevel recording. © 2003 Information Storage Industry Consortium – All Rights Reserved INSIC International Optical Data Storage Roadmap Reproduction Without Permission is Prohibited August 2003 1 Signal processing and coding have become increasingly important and powerful parts of optical data storage systems.

But, in fact, the future of optical storage is still very bright. Once theoretical methods of capacity growth, such as multi- layer, multi-level, near-field, and holographic are ready to enter the product mainstream. The engineering challenges of these advanced recording methods on lasers, media, optical pickups, servos, and read/write channels will be significant, but achievable.

  • The Role and Experience of Inventors and Start-Ups in Commercializing University Research: Case Studies at the University of California
    Research & Occasional Paper Series: CSHE.6.02 UNIVERSITY OF CALIFORNIA, BERKELEY http://ishi.lib.berkeley.edu/cshe/ THE ROLE AND EXPERIENCE OF INVENTORS AND START-UPS IN COMMERCIALIZING UNIVERSITY RESEARCH: CASE STUDIES AT THE UNIVERSITY OF CALIFORNIA December 2002 Robert A. Lowe Graduate School of Industrial Administration Carnegie Mellon University Tech and Frew Streets Pittsburgh, PA 15213 [email protected] Copyright 2002 Robert A. Lowe all rights reserved. This working paper is not to be quoted without the permission of the author. ABSTRACT This chapter from the author’s dissertation summarizes findings from case studies of university- based start-up firms. The case studies contribute descriptive accounts to support and illuminate emerging empirical research on this specialized set of start-ups. The case studies highlight several interesting findings related to the special role of inventors and the university in developing the technology as well as how the operating experience of these firms compares and contrasts with standard beliefs about start-ups. For example, the case studies document the stark contrasts among university-based start-ups with respect to both the importance of intellectual property and the company's ability to access venture capital. The case studies also highlight the importance of the inventor's personal (or tacit) knowledge in developing the technology. Finally, university inventions in the electronics and semiconductor fields, unlike pharmaceuticals and biotechnology, were the result of research that had been conducted years earlier in corporate laboratories. Hence, technology was transferred into the university. 1 Introduction Firms founded on university inventions have been an important, and often controversial, feature of the U.S.
