IBM 3490-D41
The 3490-D41 is a 36-track, 1 Control Unit,
1-drive, tape subsystem. The 3490 Enhanced
Capability (3490E) Model D41 is a member of the
IBM 3490 Magnetic Tape Subsystem family,
providing significant performance and cartridge
capacity improvements to mid-range and
intermediate customers. The D41 uses the
existing cartridge system tape and are read-
compatible with earlier cartridge system
formats, providing for ease of migration. The
Enhanced Capability format (36-track
bidirectional recording), together with standard
Improved Data Recording Capability (IDRC),
significantly increases overall cartridge
capacity. This increased capacity and optional
Automatic Cartridge Loader (ACL) combine to
address the data capacity issues of unattended
tape operations. Improved utilization of ES
Connection* (ESCON*) Channels provides new
possibilities in performance, connectivity, and
remote tape operations. |
