Using the DVD-ROM Drive: Hitachi GD-7500 12X DVDROM
User’s Guide
Operating the Drive
Drive operation
1. Turn on your system, including the DVD-ROM drive.
2. To open the DVD-ROM disc tray, press the OPEN / CLOSE button.
3. Place the disc in the center of the disc tray with the label side facing up.
4. To close the disc tray, press the OPEN / CLOSE button on the DVD-ROM drive or
push lightly on the center of the disc tray. The disc tray will automatically close.
Usage guidelines
• Keep the disc tray closed when not using the DVD-ROM drive.
• Do not press down on the disc tray when opening or closing it.
• Do not place objects on the disc tray.
• Never use a damaged, broken, or deformed disc.
• Do not press the Open/Close button while the drive is playing a DVD movie. To stop
a DVD movie, click the Stop button in the DVD player application program.
• This drive is designed to respond to the region code that is recorded on a DVD disc.
If the region number described on the DVD disc does not match the drive region,
playback will not be possible. Refer to your software manual for help. If you are
using the drive as a data only device, you will not be able to play DVD Video
(movies).
Copy Protection and Regional Coding
The Motion Picture Industry requires that DVD Drives conform to the Contents Scramble
System (CSS) to prevent copying DVD movies from DVD discs. To obtain a CSS license,
the drive must conform to two copy protection elements known as Copy Protection and
Regional Coding.
Copy Protection and Content Scramble System
The DVD drive contains the Content Scramble System (CSS) which controls the Copy
Protection. The DVD drive’s CSS system undergoes an authentication process using the
DVD disc. DVD Disc producers (normally movie DVD Discs) incorporate specialized
software on the DVD disc from which the DVD drive can authenticate. Once the
authentication process concludes, the drive can play the movie disc, but will not allow the
drive to provide digital data for the purpose of replicating the DVD disc content.
Regional Playback Control
The motion picture industry divides the world into six regional "zones". These regions or
"zones" correlate to the regional markets into which the motion picture industry releases
movies. Each regional zone is numbered "One" through "Six", called the Region.
Region One North America
Region Two Western Europe, Japan & Middle East
Region Three Southeast Asia
Region Four Mexico, Central & South America, Australia
Region Five Africa, Russia, Eastern Europe
Region Six China
DVD movie discs are released for each region and are controlled by each region. The
RPC code prevents the new release of movies into other motion picture market regions
prior to their true release dates within those markets. All DVD movie discs are coded for
one or more regions. RPC Codes are placed on Movie Discs that correlate to the region
they are intended for sale. A DVD Drive must likewise be set to a region. For example, a
PC user located in Canada, would have their DVD Drive set to Region One, or a PC user
located in France would have their drive set to Region Two. A DVD disc can only play on a
DVD drive coded for its region. The Canadian PC user could only play Region One
coded Movie DVD discs and a French PC user could only play Region Two coded movie
discs. The Regional Playback Control system does not allow users to play DVD discs that are
not set for their drive. If a user attempts to play a DVD movie disc for a region the DVD drive
is not set, the user will receive an error message explaining the DVD title is of another region
and cannot be played. DO NOT RESET THE REGION.
Setting and Changing the Region Setting of the DVD Drive
To play a DVD movie, the drive must first be set to a Region. Several methods are
available to set the region, which are transparent to the user.
• The Manufacturer may set the region at the factory
• If no region is set at the factory, most software will set the drive to the region
coded on the first movie DVD disc that is played.
• If the first disc is a multi-region coded disc, the drive will be set to the region
determined by such factors as time zone, or language etc. set into the operating
system.
Once a drive is set to a region, the region can be reset, but for unusual circumstances
only, such as when a user relocates to another region. A REGION CAN ONLY BE
RESET FOUR times. Refer to your movie player software manual for specifics about
changing the region. In general, to reset the Region, use a DVD movie disc set to the new
region. A notification box will respond, explaining the disc belongs to another region and
cannot be played. The notification explains the region setting can be reset. Follow the
instructions to reset the Drive.
NOTE: High-speed drives spin the disc at a high rotational speed. If a CD has printing on only
half of the disc, or if there is a slight imbalance in the CD, the imbalance is greatly magnified
by the high speed, causing the drive to vibrate or produce a fan-like noise. These effects are
inherent in the high-speed technology and do not indicate a problem with the drive.
Emergency Ejection (use only in the case of an emergency)
If the disc tray does not open when the OPEN / CLOSE button is pressed:
1. Make sure that the power of the DVD-ROM is turned on.
2. Make sure the lock function has not been activated.
3. Try shutting down your system and turning off all power.
4. Turn power on again and try pressing the OPEN/CLOSE button again.
5. If the disc tray still will not open, the DVD-ROM drive’s manual emergency mechanism
may be activated.
6. Turn off the DVD-ROM drive and wait at least 15 seconds until the disc stops rotating.
7. Insert a straightened paper clip into the manual emergency eject hole about 25mm (1
inch) to eject the tray.
8. Pull the disc tray open gently.
NOTE: If it is necessary to use the emergency eject procedure to open the drive, the tray should
be closed by turning on the power and pressing the OPEN / CLOSE button. Transporting the
drive before it has been properly closed may cause damage to the mechanism.
Handling media
DVD media is more sensitive to dust and fingerprints than CD media. Carefully handle media by
its edges only. If a DVD movie skips or hangs during playback, clean the media. Most DVD
video playback issues are media-related and can be solved by proper handling and care of
media.
Cleaning Media
A commercially available “Laser Lens Cleaning” may be used to clean the pick-up lens of the
DVD-ROM drive. Use the Compact Disc Laser Lens Cleaner LLC-1 (by AUDIO SOURCE in
U.S.A., by Akustik Sisteme Vertriebs GMBH in Germany and by SAEC COMMERCE CO., LTD.
in Japan.
1. Turn on the DVD-ROM drive.
2. Press the OPEN/CLOSE button to open the tray.
3. Using the small brush supplied with the cleaning disc case, straighten up the disc
cleaning brushes on the back of the cleaning disc.
4. Place the cleaning disc in the disc tray with its arrow marked on the discs at front.
5. Press the OPEN/CLOSE button or push the center of the disc tray lightly and close the
disc tray.
6. After about 20 seconds, the pick-up lens is cleaned by the cleaning disc.
7. Press the OPEN/CLOSE button and remove the cleaning disc.
8. Set the cleaning disc in its case with the disc cleaning brushes in the pad hole.
9. Restart the system.
