26 Safeguards Against LAN Data Loss The Inside Story	We test single-medium tape drives for backing up midrange networks--DAT, QIC, 8-mm, and DLT - by Tadesse W. Giorgis and John McDonough
The Technology Behind 4-MM DAT Drives THE BEST LAN SOLUTION FOR LOCAL BACKUP... OUTSTANDING NT PERFORMANCE RAW-SPEED LEADER Helical Scan Conner Storage Systems MS8000DAT Storage Dimensions TDB-8005 Hewlett-Packard JP JetStore 6000e Hewlett-Packard HP JetStore 6000e CD-R Backup Systems Compete With Tape ADVANTAGES	Helical-scan technology used on 4-mm DAT drives records large amounts of data on very-slow-moving tape.
How We Tested HP Pushes Automated Netware HP LABS Tape- Rotation Strategy	We tested the 26 tape-backup subsystems using a hierarchical file structure with five directories and three subdirectory levels.
QIC Drives TABLE OF QIC FEATURES QIC Drives	The many standards of the QIC-based recording technology write data to tape using a complex multihead assembly.
8-mm Videocassette Drives FEATURES OF 8-MM DRIVES 8-mm Videocassette Drives	As in 4-mm DAT drives, helical-scan technology constitutes the basic recording technique for 8-mm videocassette tape drives.
DLT Drives TABLE OF DLT FEATURES Quantum DLT Drives	The DLT technology is based on a high-capacity, streaming-cartridge tape that uses a dual-channel read/write head and DEC's proprietary data-compression and compaction schemes.
Standards for Compatibility Low-End QIC Gets a Capacity Boost ENTRY-LEVEL QIC STANDARDS Greater Compression for Better Data Storage	SMS (Storage Management System) is Novell's standard architecture for supporting file systems under NetWare. - by Selinda Chiquoine
The Backpack Hits 900 The Lightweight Backpack	Micro Solutions Computer Products ((800) 890-7227 or (815) 756-3411; fax (815) 756-2928) has introduced a new member of its popular Backpack series of parallel-port drives--the Backpack 900. - by Stanford Diehl
Honorable Mentions Portable Drives The Proper Terminator	The sneakernet era may be coming to an end, but network administrators may occasionally want to carry DAT drives to different locations because of no direct network link or a disruption in the communications line.
Dubious Achievement Dubious Distinction	In addition to its internal command set, the beau ty of the SCSI standard is the way physical connections have snap-on ease.
