The FileSafe 2100 is an 8mm (Exabyte) drive. The tapes used are standard 8mm videotapes (consider buying them from the local K-Mart at a fraction of what DEC charges), but the transport is different than that used in 8mm video. It was developed by Exabyte, who, as far as I know, still makes all of the drives used for data storage. DAT (Digital Audio Tape) is a different story. The tapes and transports used for DAT are the same for both audio and data applications, and are made by several different manufacturers. DAT tapes are half the width of Exabyte tapes: 4mm. -- Dave Sill (de5@ornl.gov) Martin Marietta Energy Systems Workstation Support
