AITi260 Tape Drive
The Sony AITi260 drive is a high capacity data storage device using
Advanced Intelligent tape (AIT) technology. The AITi260 drive achieves
high data reliability through Read-After-Write, an additional level of Error
Correction Code, and other features.
The Sony AITi260 drive stores data on tape using a standard format called
AIT (Advanced Intelligent Tape) and ALDC formats.

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.
• 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, the driver will be reset and
there is a risk of lost and unreadable data. Thus, please do not use the
hole other than repair purposes. (See page 13)
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.

Notice of SCSI Termination
The AITi260 conform to the Microsoft PC97 standard which requires the
internal (naked) drive to be terminated with an external 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.

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 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.
AIT-1 AIT-2, 3
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
In case of AITi260 series, a cleaning function is built into the drive and
hence the use of a c leaning cartridge is not needed. If however the drive
experiences excessive errors, the use of a cleaning cartridge is
recommended.

Emergency Cassette Removal Procedure
In case the tape is stuck inside the drive, you could remove the tape
cartridge manually.
1 Remove the drive from the chassis or enclosure to allow
access to the bottom and right side of the drive.
2 Remove the drive’s top cover.
3 Locate the small opening in the bottom of the drive and
insert the tip of a precision screwdriver so that the
Threading motor shaft can be rotated.
4 Rotate the motor shaft counterclockwise to bring the
threading mechanism back to the initial position. (Refer
to the photo-1 on page 17.)
5 Before manual eject procedure, tape slack must be
removed in order to prevent tape damage. Press and
rotate the gear mechanism located on the right side of
the drive clockwise to tighten the tape.
6 After the tape slack has been removed, turn the screw
located on the right side of the drive clockwise by a
precision screwdriver until the tape cartridge is lifted out
of the drive mechanism and is ejected.
