The Spectra T950 library provides two TeraPack Access Ports (TAPs). You can use both 
TAPs when importing or exporting TeraPack containers or media packs.

The function of each TAP, like that of an EE port, is to permit the operator to load and 
unload media. However, the TAP provides these additional key advantages:

The TAP is simply an access point, so media is never stored in the TAP. 

Newly inserted TeraPack containers and media packs are automatically pulled into the 
library, and TeraPack cases and media packs ready to be exported are not moved to a 
TAP unless an operator requests the export move using the library’s front panel. Since 
TeraPack cases and media packs are never left unattended and accessible, this provides 
added security for data, and helps to further ensure the integrity of data backups.

Operators always handle a pack of tapes at a time rather 

than individual cartridges, greatly reducing the time spent on import and export tasks.

Library operators and administrators can readily access a requested tape or tapes, even 
though the library presents the requested item or items in a TeraPack case. When an 
operator requests a specific tape, the library delivers the cartridge, in a TeraPack case, 
to the TAP. The requested tape cartridge may be presented to the operator in a 
TeraPack case that contains other cartridges; in that case, the operator simply removes 
the requested cartridge from the pack and leaves the rest. When the TAP is closed, the 
TeraPack case with the remaining cartridges is inventoried and moved back into the 
library.
