This service manual provides a variety of
service information.
It contains the mechanical structure of the Blu-
ray Disc Rewriter Drive and the electronic circuits in
schematic form. This Blu-ray Disc Rewriter Drive
was manufactured and assembled under our strict
quality control standards and meets or exceeds
industry specifications and standards.
This Blu-ray Disc Rewriter Drive is an internal
drive unit designed for use with suitable PC for Blu-
ray disc.
It can write as much as 700 Mbytes of digital
data into CD-R/RW disc, and can read as much as
700 Mbytes of digital data stored in a CD-
ROM/R/RW disc.
It can write as much as 4.7 Gbytes of digital
data into DVD-R/RW/RAM/+R/+RW disc, and can
read as much as 4.7 Gbytes of digital data stored in
a DVD-ROM/R/RW/RAM/+R/+RW disc.
It can write as much as 8.5 Gbytes of digital
data into DVD+R DL/DVD-R DL disc, and can read
as much as 8.5 Gbytes of digital data stored in a
DVD-ROM DL/+R DL/-R DL disc.
It can write as much as 25 Gbytes of digital data
into BD-R/RE disc, and can read as much as 25
Gbytes of digital data stored in a BD-ROM/R/RE
disc.
It can write as much as 50 Gbytes of digital data
into BD-R DL/RE DL disc, and can read as much as
50 Gbytes of digital data stored in a BD-ROM DL/R
DL/RE DL disc.
This Blu-ray Disc Rewriter Drive can easily meet
the upcoming MPC level 3 specification, and its
Enhanced Intelligent Device Electronics (E-IDE) and
ATAPI interface allows Plug and play integration in
the majority of today’s PCs without the need of an
additional interface card.
