This article discusses one of the new information technologies, CD-ROM, and its role in information dissemination. A review of the history of information dissemination after the Second World War, from the beginning of indexing to the emergence of databases such as Dialog, Orbit, and Questel, is the introductory discussion of the article.

The Leading Edge, 1989
Optical disk storage is a rapidly evolving technology that is creating a significant impact on the geophysical industry. Optical disks can be used to store images (drawings, surveys, maps, etc.) or raw data (seismic traces, telemetry, etc.) for retrieval and analysis.

Optic disk contractility in morning glory disk anomaly
Journal of American Association for Pediatric Ophthalmology and Strabismus, 2018Morning glory disk anomaly is a nonhereditary, congenital optic disk dysplasia characterized by conical excavation of the posterior fundus with a central glial tuft and radial retinal vessels. We report the case of a 4-year-old girl who presented with esotropia, enophthalmos, no light perception, and afferent pupillary defect in her left eye; fundus ...

Periodic structures ranging from crystal lattices through steel rulers to radio-antenna arrays may act as diffraction gratings. Because compact disks are so familiar to our students, their use as reflection gratings has become popular.

Optic Disk Size in Ischemic Optic Neuropathy
American Journal of Ophthalmology, 1988We measured the horizontal diameter, vertical diameter, and area of the optic disk in fellow eyes of patients with unilateral nonarteritic ischemic optic neuropathy and in control eyes without ocular disease. The fellow eyes of patients with anterior ischemic optic neuropathy had a smaller horizontal than vertical disk diameter (P less than .05), a ...

The Electronic Library, 1986
Descriptions of optical disk equipment usually begin with terms like CD‐ROM or WORM, leaving the reader to grope for some understanding of what the equipment does. In that frame of mind, it can be difficult to think of creative ways to use the huge capacities offered by optical disks.

Optic disk drusen (ODD) is a much more prevalent condition than it is usually considered. It is important to recognize ODD in order to escape serious neurosurgical interventions and rule out the development of optic neuropathy leading to grave visual dysfunction. Three cases with ODD are described.

Communications of the ACM, 1984
Commercially available only recently, the optical disk drive uses a laser beam to burn impressions onto a plastic disk. Employing a highly focused beam rather than a diffuse magnetic field to write, the laser optical disk drive yields storage densities up to 10 times those of magnetic disks.
