Trang 2The Cheetah disc drive is produced by Seagate Technology, Scotts Valley, California, and has been dubbed the industry’s fastest disc drive The Cheetah is the world’s first-announced drive to utilize 10,000-rpm technology The increased rotational remarkably increases data transfer rates to 15 Mbytes/sec which is 40% greater than that
of 7,200-rpm drives The 10,000-rpm rotational rate also significantly reduces the seek time
Seagate’s pioneering of the 10,000-rpm technology enables OEMs, VARs, and system integrators to take advan-tage of performance levels that were previously unattainable Seagate has developed and manufactured some of the industry’s highest-performance disc drives which not only enable users to achieve higher levels of system performance, but will also introduce exciting new electronic applications (Photo courtesy of Seagate Technology.)

HE TRULY INCREDIBLE CHANGES in the technology associated with electronics over the past three decades have certainly been the driving force for most of the growth in the field of electrical engineering Recall that 30 years ago the transistor was a novel device and that the majority of electronic systems still used vacuum tubes Then look at the section headings in the following chapters and appreciate the range
of ways that electronics has impacted electrical engineering Amplifiers, integrated circuits, filters, power electronics, and optoelectronics are examples of how electronics transformed the practice of electrical engi-neering in such diverse fields as power generation and distribution, communications, signal processing, and computers
The various contributors to this section have done an outstanding job of providing concise and practical coverage of this immense field By necessity, the content ranges from rather theoretical considerations, such as physical principles of semiconductors, to quite practical issues such as printed circuit board technology and circuits for active filter realizations There are areas of overlap with other chapters in the Handbook, such as those covering electrical effects and devices, biomedical electronics, digital devices, and computers The con-tributors to this section, however, have maintained a focus on providing practical and useful information directly related to electronics as needed by a practicing electrical engineer
The author(s) of each chapter was given the task of providing broad coverage of the field while being restricted
to only a few pages of text As a result, the information content is quite high and tends to treat the main principles or most useful topics in each area without giving the details or extensions of the subject This practice, followed throughout the Handbook, is what makes it a valuable new work in electrical engineering In most cases the information here will be complete enough When this is not the case, the references will point the way to whatever added information is necessary
