Storage digital data

The CD-I (compact disk-interactive) is a low cost alternative to the CD-ROM for the entertainment industry. CD-I is a subset of the CD-ROM standard data format. It allows the digital storage of data, audio, and video information in a form that permits rapid interaction with a computer. CD-I is compatible to CD-ROM and to CD-AD 0 = 120 mm. The definition of the CD-I format is put down in the Green Book (Philips/Sony). 

Over the years, many instruments have been developed for and used in the scientific laboratory. Today, the computer is used as a major tool in the scientific laboratory for the capture, manipulation, transfer, and storage of data. Consequently, the concern for data quality has shifted from the instruments that are used in the generation of the data to these electronic systems, often neglecting the fact that the data are only as accurate as the instrument measurements. For instance, many electronic systems can be used in chromatography analysis, from the electronic log book where the test substance inventory is kept, throughout data capture in the instrument, to the digitized electronic signal that is the raw data on the computer network. For crop residue samples, the... 

A further development using digital data storage allows the simultaneous measurement of different masses [12],... 

We must emphasize that in this extremely brief introduction to magnetic properties we have only scratched the surface of this wide-ranging topic. Because magnetic properties lie at the heart of most digital data storage techniques, the numerous phenomena associated with magnetism have been the subject of intense worldwide research for decades. The Further Reading section lists several resources that can provide an entry point into this topic. 

In addition to their role as teehnology enablers, ceramic components find widespread use today in elee-tronics, wireless communications, fiber optie eables, lasers, digital data storage, and eapaeitors. Emerging technologies in which ceramics play a key role inelude... 

The two most popular data-acquisition systems are the strip-chart recorder and the digital data-storage system. The latter is used when a great deal of data processing is anticipated. 

Phase sensitive. The collection of an NMR data set involving the use of a 90° phase shift in the receiver and also possibly in the phase of one of the RF pulses of the pulse sequence, thus allowing the storage of the digitized data points into two separate memory locations to allow phase correction during processing.
