that stress the tape. DLTtape rollers are large and are arranged in a
gentle arc along the HGA. This roller arrangement results in much
less wear than in helical scan system.
When a DLTtape cartridge is inserted into the drive, it is automati-
cally locked into position. A patented buckling mechanism pulls the
DLTtape media from its cartridge. Unlike 8mm and other cartridge
tape systems, DLTtape cartridges have a supply reel, but no take-up
reel. The tape is pulled along the tape path (see Figures 5-3 and 5-4)
to a take-up reel mounted permanently inside the drive. In this way,
no space is wasted inside the DLTtape cartridge, allowing for more
tape per cartridge. This design means the DLTtape system lets you
store more data in less space than other tape systems.
Tape Handling
The half-inch DLTtape media passes across the drive's write/read/
write head under very low tension. The only time the head moves is

a gentle curve that reduces tape wear and ensures tracking accuracy.
