Overview
The Sony AITi260, AITi130, and AITi90 drives are high capacity data
storage devices using Advanced Intelligent tape (AIT) technology. The
AITi260, AITi130, and AITi90 drives achieve high data reliability through
Read-After-Write, an additional level of Error Correction Code, and other
features.
The Sony AITi260, AITi130, and AITi90 drives store data on tape using
standard formats called AIT (Advanced Intelligent Tape) and ALDC
formats.

Introduction
About AIT Drives
The AITi260 is an internal AIT drive unit that uses data cartridges conforming
to the AIT-3 format. The AITi130 is an internal AIT drive unit that uses data
cartridges conforming to the AIT-2 format. The AITi90 is an internal AIT
drive unit that uses data cartridges conforming to the AIT-1 format. The
AITi260 supports AIT-1, AIT-2, and AIT-3 formats. The AITi130 supports
AIT-1 and AIT-2 formats. The AITi90 supports only AIT-1 format.
Features
The AIT Drive Unit AITi260 has the following features:
• The Advanced Intelligent Tape format provides a huge data storage
capacity on AIT-1/AIT-2/AIT-3 data cartridges.
• Read After Write Function and third-level error code guarantee high data
reliability.
• Data compression provides 260 gigabytes of storage on 230 m tape-
length cartridge.*1
The native capacity is 100 gigabytes of storage on 230 m tape-length
cartridge.
• Stored data are automatically checked for compression.
• Ultra 160 SCSI LVD/SE interface is fully supported for host computer
access.
• Read/Write operation is available with AIT-1, AIT-2, and AIT-3 formats.
The AIT Drive Unit AITi130 has the following features:
• The Advanced Intelligent Tape format provides a huge data storage
capacity on AIT-1/AIT-2 data cartridges.
• Read After Write Function and third-level error correction code
guarantee high data reliability.
• Data compression provides 130 gigabytes of storage on 230 m tape-
length cartridge.*1
The native capacity is 50 gigabytes of storage on 230 m tape-length
cartridge.
• Stored data are automatically checked for compression.
• Wide Ultra SCSI LVD/SE interface is fully supported for host computer
access.

• Read/Write operation is available with AIT-1 and AIT-2 formats.
The AIT Drive Unit AITi90 has the following features:
• The Advanced Intelligent Tape format provides a huge data storage
capacity on AIT-1 data cartridges.
• Read After Write Function and third-level error correction code
guarantee high data reliability.
• Data compression provides 91 gigabytes of storage on 230 m tape-length
cartridge.*1
The native capacity is 35 gigabytes of storage on 230 m tape-length
cartridge.
• Stored data are automatically checked for compression.
• Wide Ultra SCSI LVD/SE interface is fully supported for host computer
access.
• Read/Write operation is available with AIT-1 format.
*1 This is assuming 2.6 : 1 compression ratio.
The degree of data compression attained while recording data varies according to
system environment and data type.
Precautions
Installation
Avoid placing the drive in a location subject to:
– high humidity
– high temperature
– mechanical shock and vibration
– direct sunlight
Operation
• Do not move the drive while it is operating. It may cause malfunction.
• Avoid exposing the drive to sudden changes from a low to high in
temperature. This may cause water condensation to collect inside the
drive. If the ambient temperature should suddenly rise while the drive is
turned on , wait at least one hour before turning on the drive. If you
attempt to operate the drive immediately after a sudden increase in
temperature, a malfunction may occur.

6
• Turning off the power to the drive while it is writing to tape may cause
the tape to become unreadable. All previously negotiated parameters will
be lost, whenever power to the drive is cycled.
• Upon execution of the hardware reset hole with the AITi260, the driver
will be reset and there is a risk of lost and unreadable data. Thus, please
do not use the hole other than for repair purposes. (See page 14)
Transportation
• Keep the original packing materials to facilitate transportation of the
drive.
• Always remove the tape before moving the drive. After removing the
drive from the computer, repack the drive into its original packing.
SCSI Termination
The AITi260, AITi130, and AITi90 conform to the Microsoft PC97
standard which requires the internal (naked) drive to be terminated with an
internal terminator.
Microsoft PC97 SCSI requirements
SCSI peripherals must not terminate the bus. Both internal and external cable ends are
instead terminated by plug-in connectors.

Example of SCSI setup
The AITi260 supports Ultra 160 SCSI. When using an Ultra 160 SCSI
connection, make sure that you are using appropriate cables and
terminators.

Drive Operation
Loading a Cassette
Insert a cassette into the slot on the front panel with the arrow on the
cassette pointing towards the drive. As the cassette is inserted, the drive
takes it and automatically loads it into drive mechanism.
Unloading a Cassette
The cassette can be removed from the AITi260, AITi130, and AITi90
either in response to a SCSI Unload Command, or by pressing the eject
bottom.
By pressing Eject button, the tape goes to BOT, the drive unthreads it, and
ejects the cassette from the slot.
Write-protecting a Cassette
Cassettes can be write-protected by sliding the tab on the back of the
cassette. In this state, data can be read from the tape but not written onto it.
Using your fingernail, push the switch in the
direction of the arrow to protect the tape from
writing or accidental erasure.
Return the switch to its original position to
re-enable writing.

Using a Cleaning Tape
A cleaning function is built into the AITi260, AITi130, and AITi90 so the
use of a cleaning cartridge is not needed. If however the drive experiences
excessive errors, the use of a cleaning cartridge is recommended.
