The PSFK blog
has noted the latest wonder from NTT -- a clear plastic sliver called Info Mica
that stores data holographically. Announced this past February, a sliver the size of a postage stamp can hold 1GB of data. Aside from its small size, the touted advantages of Info Mica are greater security (better copy protection) and easy disposability. One early application for Info Mica is one-way data distribution, such as music or video. Therefore, Info Mica might not replace flash memory so readily as it might replace CDs and DVDs. Info Mica could also server as rich RFID tags.
