A glance at the table of contents, in volume 10, will show that some topics merit a large number of articles, a reflection of their importance in current analytical science. Several techniques, for example, mass spectrometry, nuclear magnetic resonance spectroscopy, atomic emission spectrometry, microscopy, the various chromatographic techniques (e.g., gas, liquid and thin-layer), and electrophoresis, merit a series of articles, as do areas such as food and nutritional analysis, forensic sciences, archaeometry, pharmaceutical analysis, sensors, and surface analysis. Each of these collections of articles, written by experts in their fields, provides at least as much up-to-date information on that particular subject as a complete textbook. 

Localization of both the write fields and read head sensitivity is achieved by positioning both the write head and read head sensor in very close proximity of the disk surface. The heads are bonded to the rear end of a slider that skims across the disk surface on a thin layer of air entrained by the rotating disk. Thus, the operation of a disk drive reqnires a delicate balance of mechanical, electrical, and magnetic properties, with all three optimized for both economy and performance.
