destroy this equipment and could damage or destroy the disc or cause data loss or corruption.
4.3. DO NOT load or eject any CD or DVD disc with force. Doing so will damage or destroy this equipment
and could damage or destroy the disc or cause data loss or destruction.
4.4. DO NOT eject a CD or DVD disc while the drive is in operation. Doing so will damage or destroy this
equipment and could damage or destroy the disc or cause data loss or corruption.
4.5. DO NOT insert anything else into the drive other than a CD or DVD disc. Doing so will damage or
destroy this equipment.
5. When you close the tray, power must not be turned off. If the tray is pushed in with the hand during
power off, a breakdown may occur because the mechanism in the product is not in the transit
state during power off.

6. As for mounting bracket to incorporate this product into an equipment,
(1) When this product is incorporated into an equipment by using the mounting screw holes in the right
and left side planes, the clearance between this product and the mounting bracket is too wide;
(2) When this product is incorporated into an equipment by using the mounting screw hole in the
bottom, the surface of the mounting bracket is contorted.
If you use such mounting bracket as the above, this product will become deformed, which may cause
operation failure. Therefore, it is necessary to take account of the mounting bracket which has the
tolerances shown in Fig.1 or whose structure cannot cause this product to deform, as shown in Fig.2

This drive records (write once) digital data on DVD-R disc at 1, 2, 4 times faster rotational speed.
This drive writes / rewrites digital data on DVD-RW disc at 1, 2 time rotational speed.
This drive corresponds to 4.3GB disc (single side) / 9.4 GB disc (double side) at time of reading
DVD-RAM disc and digital stored on DVD-RAM disc at standard rotational speed.
This drive records (write once) digital data on CD-R disc at 4 to 16 times faster rotational speed.
This drive writes / rewrites digital data on CD-RW disc at 4 times faster rotational speed.
This drive writes / rewrites digital data on Hight-Speed CD-RW disc at 4,10 times faster rotational speed.
This drive offers long life and durability because the disc is written / read by a LASER, thereby eliminating
physical contact with the disc.

This drive adopts RPC-II for its "Standard Specification Model".
This drive support "Buffer underrun prevention" function.
Note:
DVD-ROM disc spec (DVD-ROM Book) defines 120 mm and 80 mm in diameter, single and dual layers
as recording layer structure and single and double sides as recording side.

5.1.3. CD-R / CD-RW Data Configurations
Before writing
CD-R / CD-RW disc contains time-code information called ATIP.
ATIP is abbreviation of "Absolute Time In Pre-groove" in the wobbling groove by modulating
the carrier frequency.
(Address information is pre-formatted to ATIP on the CD-R / CD-RW disc and method for the
guide groove to wobble by FM modulation.)
Figure 6 shows the composition of ATIP.

5.1.4. DVD-R/-RW Data Configurations
Before writing
DVD-R / -RW disc contains ECC block address embossed as the pre-pit information on the land.
The ECC block address is the absolute physical of the track., and corresponds to 16 sector, equal in
size to 1 ECC block to be recorded in the groove.
