Rewritable optical disk drive technology

Optical disk drives provide an effective solution to the growing need for removable high-capacity storage. In this paper, we review the technology behind the optical disk drives used in IBM’s optical storage systems. The basic physics of data recording and readout and the engineering of the primary building blocks of an optical drive (the optical head, the servo system, and the data channel) ar...

Using Compiler Technology to Drive Advanced Microprocessors

Recent years have seen the introduction of a series of ever faster, ever more complex microprocessors. These advanced microprocessors have found widespread application in machines that range from personal computers to engineering workstations to massively parallel multicomputers. Unfortunately, many of the features used to endow these processors with high peak performance numbers are diicult fo...

Review of Variable Speed Drive Technology By

Variable speed drive technology has advanced dramatically in the last 10 years with the advent of new power devices and magnetic materials. This has given rise to substantial confusion by users and specifiers of variable speed drive equipment. Add to that the difficulty in evaluating efficiency and power factor and the subject of drive selection becomes a daunting task indeed. There is no singl...

Where Will Object Technology Drive Data Administration?

Several unifications that the application development process has long needed are now occurring, due to developments in object technologies and standards. These will (gradually) change the way data intensive applications are developed, reduce databases’ prominence in this process, and change data administration’s goals and participants. At the same time, the database community needs to ensure t...
