Overview
The Sony SDX-900V series drives are high capacity data storage devices
using Advanced Intelligent tape (AIT) technology. The SDX-900V series
drives achieve high data reliability through Read-After-Write, an additional
level of Error Correction Code, and other features.
The Sony SDX-900V series drives store data on tape using standard
formats called AIT (Advanced Intelligent Tape) and ALDC.
6
Introduction
About AIT Drives
SDX-900V series drives are internal AIT drive units that use data cartridges
conforming to the AIT-4 format.
Features
The SDX-900V series drives have the following features:
• Support reading and writing to data cartridges conforming to the AIT-4
format.
• The Read-After-Write Function and third-level error correction code
guarantee high data reliability.
• Data compression provides 520 gigabytes of storage on 246 m tape-
length cartridge.*1
The native capacity is 200 gigabytes of storage on 246 m tape-length
cartridge.
• Stored data is automatically checked for compression.
• Ultra 160 Wide SCSI LVD/SE interface is fully supported for host
computer access.
*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.
7
Precautions
Useable Cartridges
SDX-900V series can be used with data and cleaning cartridges marked
with the AIT-4 logo.
Notes
• Be sure to use only data cartridges designed specifically for AIT (do not use 8 mm
video cartridges) as this may damage the drives.
• Do not use anything but AIT cartridges with this system, as doing so can damage the
AIT drive. Although commercially available 8mm videotapes resemble AIT cartridges
in appearance, they have entirely different specifications and cannot be used.
Installation
Avoid placing the drives in locations subject to:
– high humidity
– high temperature
– mechanical shock and vibration
– direct sunlight
* For details, see “Specifications” on page 26.
Operation
• Do not move the drives while they are operating. It may cause
malfunctions.
• Avoid exposing the drives to sudden changes from low to high
temperatures. This may cause condensation to collect inside the drives. If
the ambient temperature should suddenly rise while the drives are turned
on, turn them off and wait at least one hour before turning them back on.
If you attempt to operate the drives immediately after a sudden increase
in temperature, malfunctions may occur.
• Turning off the power to the drives while they are writing to tape may
cause the tape to become unreadable. All previously negotiated
parameters will be lost, whenever power to the drives is cycled.
8
Transportation
• Keep the original packing materials to facilitate safe transportation of the
drives.
• Always remove the tape/media cartridge before moving the drives. After
removing the drives from the computer, repack them into their original
packing.
SCSI Termination
The SDX-900V series drives 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.

Attaching and Removing the Dust
Cover
Attaching the Dust Cover
1 Align the dust cover’s hinge clips (one on each side) with the
pins of the drive bezel.
•
The dust cover should be positioned so that the magnets* on the
cover’s back face the drive bezel.
* This magnet does not affect the tape of the cartridge.
•
Holding the dust cover at an angle, as shown in the figure below,
set the hinge clips on top of the bezel pins, positioning them so that
they bracket the pins.
17
2 Press down at an angle on each side in turn until you hear
the hinge clips click into place.
Caution
Do not press the dust cover in horizontally from the front. Doing so
could cause the dust cover to break.
3 Close the dust cover.
This completes attachment of the dust cover.
18
Removing the Dust Cover
1 Open the dust cover.
2 Holding the dust cover at both corners, carefully raise the
dust cover.
The dust cover hinge clips and drive bezel pins uncouple.
Note
We recommend that you use the drive with the dust cover.

Drive Operation
Loading a Cartridge
Note
While setting the data cartridge, do not turn off the host computer. This
may cause a malfunction or damage data.
1 Turn on the host computer. Check that the drive’s TAPE
MOTION LED, CLEANING REQUEST LED and REPLACE
TAPE LED go off.
2 Open the dust cover.
3 Set the AIT data cartridge orientation as shown here and
insert it into the data cartridge slot.
By fully inserting the data cartridge, it is automatically set in the drive
and the TAPE MOTION LED lights.
21
Unloading a Cartridge
The cartridge can be removed from SDX-900V series drives in response to
a SCSI Unload command, or by pressing the EJECT button.
When the EJECT button is pressed, the tape is rewound and the cartridge
ejected from the slot.
Write-protecting a Cartridge
Cartridges can be write-protected by sliding the tab on the back of the
cartridge. In this state, data can be read from the tape but not written onto it.
AIT-4
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 Cartridge
A cleaning function is built into SDX-900V series drives so the use of a
cleaning cartridge is not needed. If, however, the drive experiences
excessive errors, use a cleaning cartridge with the AIT logo.
How to Clean
1 Load the head-cleaning cartridge (SDX4-CL) into the SDX-
900V. Cleaning starts automatically.
2 Cleaning takes from a few seconds to a minute for the SDX-
900V, *1 and the cartridge is automatically ejected when
finished.
*1 The cleaning time varies depending on the condition of the drive.
