High density digital magnetic and magneto-optical storage devices are widely used in audio, video, and data processing information technology, as well as in CAD/CAM computer systems. These widespread uses generate a continually increasing demand for both increased information storage densities and capacities, and for reduced access times. Hence, the materials engineering of high density storage media, with a high signal to noise ratio, and the associated design of sophisticated read and write heads, form the basis of major technological research. This research is especially complex because, ideally, the recorded information should be both erasable and, at the same time, secure and accessible over periods of many decades. As a result, research on these complex problems requires a multidisciplinary approach which utilizes the expertise in such widely differing fields as organic, inorganic, and solid state chemistry, metallurgy, solid state physics, electrical and mechanical engineering, and systems analysis. Often, further research specialization is necessary in each of these different disciplines. For instance, solid state physics and chemistry address the problems of crystallographic structure and phase diagram determination, magnetism, and optics, but more advanced research methods, such as high resolution electron microscopy and electronic band structure calculations, are necessary to understand the microstructure of particulate recording media or the electronic spectra of magneto-optical recording media.

A high-density digital recording system is described that allows the conversion from analogue to digital form of up to twenty input analogue channels, their recording on magnetic tape, their readback from tape, and their transfer to a digital computer. The heart of the system is a standard 14-track analogue instrumentation tape-recorder, of the wide-band type, working in direct-recording mode at a speed of 30 in/s and used for digital recording at a density of about 12 kilobits per inch and per track. A total data recording rate of 2880 kilobits per second is achieved with ten magnetic tracks. The system has been successfully tested during various sea trials and is now fully operational. (Author).

The state-of-the-art in High Density Digital Data Recording is such that it is now possible to evaluate the capabilities of write-once-read-many (WORM) laser disc systems vis-a-vis magnetic tape spooling. Most of such a systems' components can be purchased off the shelf. The potential to store unalterable data, in vast amounts, in a small space, or a medium impervious to time degradation can be realized with current technology.
