Built-in AIT
This chapter explains setup, installation and daily operation of the N8551-28F/N8151-44F Built-In
AIT.
Features
This unit has the following features:
•You can record large amounts of data on the AIT1 and AIT2 data cartridges using AIT (Ad-
vanced Intelligent Tape) format.
•When the data compression function is used, an AIT2 (tape length: 230 m) data cartridge can
store 50 to 100 GB of data, an AIT1 (tape length: 230 m) data cartridge can store 35 to 70 GB of
data, and an AIT1 (tape length: 170 m) data cartridge can store 25 to 50 GB of data.
•The basic processing unit automatically determines whether data recorded on the AIT data
cartridges is compressed. It can also read data recorded on AIT data cartridges with conven-
tional AIT drives.
*1 The compression rate for recorded data may differ depending on the user environment and
the type of data.
(When using an average compression rate of 2.)
Usable Cartridges
Please use Sony AIT data cartridges (AIT2 (tape length: 230 m), or AIT1 (tape length: 230 m),
(tape length: 170 m)) with this unit. Using other types of AIT data cartridges may cause read and
write errors.
