A CDE Definition
(1) A framework for writing Web-based applications in Java from the Apache Jakarta Project. See Jakarta.
(2) A holographic optical disc from InPhase Technologies, Longmont, CO, designed for archiving data and video. InPhase was a spin-off of Lucent Technologies in 2000, and Tapestry was the first commercial holographic storage. In 2010, production began for a 300GB write-once, removable optical cartridge. However, InPhase went bankrupt in 2011, and Akonia Holographics acquired its assets in 2012 (www.akoniaholographics.com).
A Disc That Didn't Spin Continuously
Containing a photo polymer recording layer in the middle, the single platter was divided into thousands of optical "books" roughly one cubic millimeter in size. For reading and writing, the disc was rotated to the appropriate book, which held 330 1.4Mbit "binary holograms" (patterns of digital bits). Each hologram was recorded with one flash of a blue laser, and the amazing thing is that every hologram fully occupied the same physical space in the book. For more details, see holographic storage.
