DD0401 Dual DVD Recorder -
proceeds on to 8x dual recording with it's new DD0401 ATAPI burner.
The Taiwanese manufacturer has already gained momentum in the optical storage
the successful DD0203, released some months ago. Based on the Sanyo chipset,
possibly the biggest manufacturer of LSI for DVD recorders, the DD0401 combines
specifications at an affordable price. The drive is available in the market
for less that $150.
DD0401 uses Sanyo's Burn Proof technology to avoid buffer underun problems
when recording on CD/DVD media.
The dual burner offers 8x DVD+R, 4x DVD-R/+RW and 2x DVD-R writing and 12x
DVD-ROM reading. The drive is also a 40x/24x/40x CD-RW writer.
with previous Optorite DVD recorders, the DD0401 supports High Density
recording for CD-R media. Developed by SANYO Electric Co., Ltd., HD-BURN allows
conventional CD-R media (700MB) to double the writing capacity (1.4GB). This
is achieved by shortening the minimum pit length to 0.62µm
(0.82µm for CD-R), using more efficient modulation and a different error
correction sheme (RS- Product code). According to Sanyo, this fills the gap
between CD and DVD media, for users who require
by CD but
DVD is too much.
also features Sanyo 's "Safe-BP" technology, which stops
writing at the point of the recording error, and restarts writing
while changing the recording speed by monitoring the pickup servo in real time.
"Shock BP" developed a drive which is resistant to "shock" as
a development target function.
Of course, the most awaited feature of the new Optorite DD0401
is the supported writing speeds. The new drive offers 8x DVD+R (Z-CLV)
recording, and DVD+RW at 4x CLV. DVD-R media can be burned at 4x CLV and DVD-RW
at 2x CLV.
Writing under HD-BURN can be achieved at 24x maximum. The HD-BURN discs can
be read at 78x max, considering the increased density of the recorded data.
The maximum CD writing speed for CD-R is 40x CAV and 24x P-CAV, when using
Ultra Speed CD-RW media. Reading of CD-ROM can be done at 40x CAV maximum.
The drive is also a fast DVD reader with 12x CAV for DVD-ROM single layer and
8x for DVD±R/RW and dual layer DVD-ROM.
Optorite chose a 2MB buffer to obtain safe recordings at 8x. The drive
also supports RAW DAO 96 writing (CD).
The drive uses the RPC II region control, allowing a user to change
the drive's region at most 5 times. For our tests, we set the region
code to 2 (Europe).
- Retail package

- The drive
The drive's front panel has a few design features which differ from the stock
standard design we have come to expect. The drive tray door, occupying the
upper half of the drive, protrudes and curves outwards
slightly at the
There are the usual
DVD/CD and R/RW markings
located on the left, centre and right hand sides of the tray door, with the
the lower rim and right of centre. The lower half of the drive's front panel,
includes the headphone jack and volume control situated on the very left,
the power/activity led directly below the eject hole and right of centre,
and the next track and stop/eject buttons on the right. Both buttons are round
the stop/eject being slightly larger.
The rear panel has the standard layout proceeding from left to right -
analogue and digital audio outputs (SPDIF), master/slave select, the IDE connector
and the power input.
Removing the screws and opening the drive's cover voids the drive's warranty.
For reference reasons, we post the following photos. The Optorite DD0401's
mainboard (based on the Sanyo LC897490 chipset) and drive mechanics
have been designed by Optorite, which was not the case with their previous
the DD0203. Click on photo of the mainboard

When connected to our test PC with Windows XP operating system, the drive
was identified as "OPTORITE DVD RW DD0401". All tests were
done with firmware revision v1.20E.

with two other DVD burners, the Philips DVDR824P and
PX-708A, for comparison.
