Shell 4.08”x4.2”x.860”Although the media may look the same physically, because of differences in magnetic formulation between the different formats the media will not work interchangeably between different major product families

Although LTO and DLT media look similar they are actually slightly different sizes and have different mechanical features just as other media types 3480 and SAIT

LTO Technology HighlightsLTO Technology HighlightsLTO-2 Drive

Adaptive threading and soft load interlock

eliminate problems associated with cartridge miss-

loading

High durability mechanism designed for

automation service duty

Adaptive data rate matching provides full speed to

half speed data rate matching in 1/8 step increments

Dual Actuator Head

Provides high resolution servo tracking

improving data reliability

Superior shock and vibration performance

compared to other drive technologies

Surface Control Guiding

Surface Control Guiding eliminates traditional edge

guiding techniques providing greater media durability

Reduces debris generation and insensitive to tape edge

quality or pack dynamics
