4x DVD+R/RW Roundup - Page 1
With 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.

- The package
The retail package includes one 4.7GB 4x DVD+R disc for data/video by Ricoh, one 4.7GB 2.4x DVD+RW disc by Ricoh, a multilingual quick start manual and a manual and application software CD-ROM.
This includes the “WinDVD Creator Plus” software that offers increased recording and editing functionality for DVD+R/RW in a simple and easy to use layout.
“WinDVD™ 4” is also attached, allowing playback of all DVD and CD formats. The basic CD/DVD recording software is the “Nero Burning Rom v5” and InCD v126.96.36.199 for random access rewrite for CD/DVD .
In addition, the CD-ROM includes some arcade games for your spare time and MP3 JukeBox software, among with manuals for many Mitsumi products.
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:
