AITi130 Tape Drive
The Sony AITi130 drive is a high capacity data storage device using
Advanced Intelligent tape (AIT) technology. The AITi130 drive achieves
high data reliability through Read-After-Write, an additional level of Error
Correction Code, and other features.
The Sony AITi130 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.
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 AITi130 conforms 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 Tape
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 Tape
The cassette can be removed from the AITi130 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 Tape
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.
AIT-1 AIT-2
Using a Cleaning Cassette
In case of AITi130, 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.

16
Emergency Tape Removal Procedure
1Remove the drive from the chassis or enclosure to allow
access to the bottom and right side of the drive.
2Remove the drive’s top cover.
3Locate 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.
4Rotate the motor shaft counterclockwise to bring the
threading mechanism back to the initial position. (Refer to
the photo-1 on page 18.)
5Before 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.
6After 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.

Caution
Stop rotating the motor shaft immediately, when the guide B (see detail A of Photo-1)
gets to the area below the line C-C (This line is defined by 2 circular tape guide surfaces
of the cartridge). Otherwise the gear of the drive can be damaged.
