4x DVD+R/RW Roundup -
the CD recording era to be in its set, most of the manufacturers had to make
their own decisions and follow the market demand. And the demand is the fast
and reliable DVD recording.
The situation is not different here. Again the alternatives for chipset and
optical pickup mechanisms are limited, at least for the beginning. Additionally,
when it comes to choosing a single DVD format among the DVD plus R/RW and DVD
dash R/RW and not a multi-format format set, the available solutions come solely
from a limited sources. As a result, the first DVD+R/RW drives share the same
mechanism and any slight variations in their performance should be expected
only in specific firmware modifications.
Mitsumi demonstrated its first DVD+R/RW recorder at CeBIT 2003. According
to the company, including the drive to the Mitsumi's booth was a last minute
decision. The Mitsumi DW-7801 TE we have in our hands support 4x DVD+R writing
and was manufactured in March 2003.
Plextor also demonstrated the new PX-504A
in CeBIT. It offers the same specifications as the Mitsumi drive does, and
the model we have in our labs was manufactured
on February 2003.

Last, in the retail package you can find the usual internal audio cable, an
IDE cable and mounting screws.
On the disc loading tray you can see "DVD+RW" and the "HSRW" logos.
The eject button is placed below the tray, on the right side of the front panel,
as usual. The indication LED is active when a disc is loaded or the drive performs
a read/write task. The drive has also a headphone plug and a volume control
button, for audio CDs.
On the rear panel there are the usual connectors, such as the power input,
the ATAPI interface, the device configuration jumper, and the analog audio
output. Notice that the case was built to accept a ventilation fan but this
is not included in the Mitsumi model.
After removing the screws on the bottom we can see the drive's internal
design. You can easily recognize that the both mainboard and chips of the drive
are manufactured by NEC.
Mitsumi was identified as "MITSUMI DW-7801TE" under WinXP. The
drive was installed to the secondary IDE channel of our test PC as a "Master” and
worked in Ultra DMA Mode 2 transfer mode. The model came with firmware version
v1.01 installed, which was used for all the tests:
