Tapestry - technical 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 (www.inphase-tech.com) designed for archiving data and video. InPhase, which was a spin-off of Lucent Technologies in 2000, is the first company to commercialize holographic storage. Announced in 2002, the prototype of its first product was released in January 2005: a write-once, removable optical drive with a 300GB capacity on a single platter.

The Disc Does Not Spin
The disc, which contains a photo polymer recording layer in the middle, is divided into thousands of optical "books" roughly one cubic millimeter in size (.8 x 1 x 1.5 mm). The disc does not spin continuously; it rotates to each book region as required, and each book holds several hundred 1.4 megabit pages (digital holograms). What is most amazing is that each bit of each page completely fills and occupies the same volume of the book as does every other bit in every other page.
