Dr. Givan and others, We use WORM (Write Once Read Many) optical platters exclusively now. Previously we have used: 8-inch floppies, 9-track tape, and TK-50 tape. We're having some difficulty getting a new re-writable optical configured, so I can't comment on that yet. The WORM drive is on a MicroVAX II computer, and all FCS data is FACSnetted over. Each platter holds 400 Meg per side. In general, WORM data is good for 10 years or so, re-writable data less than that, and everything else is questionable as far as data archiving goes. (Of course, sometimes the media lasts longer than the VALUE of the data on it: the longer the data sits, the less it is reviewed, in our experience. If we didn't have the WORM/MicroVAX, we would probably get a computer to act as a file server, with a re-writable optical drive. This would allow FACS users to 'dump' their data to the server. Users could then access the data from PC work- stations for analysis (to free-up the FACS for aquisition). When done analyzing the data, it could be archived on the optical. Each user would be responsible for their own optical disk to reduce facility costs (currently our facility archives ALL data, filling expensive optical platters with data that never gets looked at after archival.) /\/\/\_ Eric Van Buren vanburen%flovax.dnet@rocdec.roc.wayne.edu \ \ \-' Immunology/Microbiology 313 577 1009 voice \_^_/ Wayne State University 313 577 1155 fax
