- Mitsumi CR-485C TE
drive supports 40x writing (Z-CLV), 12x re-writing, 2MB Buffer and "ExacLink"
as the main buffer underrun technology. The maximum reading speed is 48x (CAV).
The exact writing speeds are 4x, 8x, 16x CLV), 24x, 32x and 40x (Z-CLV). The
re-writing speeds are 4x, 10x and 12x. There will be a limited amount of drives
with increased buffer (up to 16MB), but the major amount of drives will include
The CR-485CTE supports Mitsumi's AEGIS WRITE technology with the following
Automatically check media quality and set limit to writing speed.
- Automatically optimize to OPC method and select the optimum write strategy
from the large capacity database.
- Monitor writing condition and optimize writing speed to achieve the safe speed
- Monitor the writing condition and compensate for optimum write laser power
by Mitsumi WPC (Write Power Compensation) technology.
Additional and essential knowledge is required for successful high-speed CD
· Understanding of CD media characteristics
· Knowledge of various types of CD media
· Identifying and determining the best recording speed for the media
· Identifying and determining the best recording method
· Understanding of CD recording conditions
AEGIS WRITE is designed with CD recording intelligence so the user can focus
on what to record onto CD, while AEGIS WRITE focuses on providing a successful
CD recording session each time.
you can find a presentation of Mitsumi's "AEGISWRITE" system. In Greek
mythology, AEGIS is the name of the shield Zeus gave to his daughter Athena.
AEGIS means The shield that protects from all evil.. To provide
users with the best in recording speed and quality, Mitsumi combined its
already popular high-quality recorders with Mitsumis original safe and
easy recording technology, and created AEGIS WRITE.
A nti-coaster: AEGIS WRITE is equipped with Exac-Link buffer under-run
protection technology; enabling successful CD recording sessions and eliminating
CD coasters.. Buffer under-runs occur when the data transfer speed
from the PC cannot keep up with the recording speed of the CD recorder. The
CD recording session fails thus creating a coaster. AEGIS WRITE
can temporarily stop data transfer BEFORE the buffer under-run occurs, protecting
the CD recording session.
E asy: AEGIS WRITE makes CD recording easier with its ability to detect
disc quality. Insert the disc into the CD recorder and AEGIS WRITE does the
G uard: AEGIS WRITE monitors the CD recording session with its Write
Condition Monitoring System. This enables AEGIS WRITE to adjust the recording
speed based on the changing conditions of the recording process, thus providing
additional protection to guard against CD recording failure.
I ntelligent: AEGIS WRITE has an extensive database of CD media profiles
based on Mitsumis research and studies of media recording characteristics.
AEGIS WRITE refers to the database to select the most suitable laser shape and
power to insure a high quality CD recording.
- Mt. Rainier
The drive does support the Mt. Rainier format, and Mitsumi says that it is
the only drive compatible according to Philip's EasyWrite testing suite. The
following test results come from the last Mt. Rainier Plugfest.
- 40x CD-R writing speed
The Mitsumi drive supports the 40x writing speed with the use of the Z-CLV
writing technology. Below it's the Nero CD Speed writing graph that illustrates
the use of Zone-CLV:
The 40x writing speed range is divided in 4 zones: The drive starts writing
at 20x from the lead-in area till 6mins, shifts up to 24x at 10mins, up to 32x
at 32mins and lastly shifts to 40x at 60mins and stays there until the end.
The average recording speed is 29.63X, as Nero CD Speed shows. The average
writing speed of the Mitsumi drive makes it slower than what the competition
offers. According to CDR software the drive doesn't seem to lower its maximum
recording speed but judging from the final recording time, you can understand
if the drive dropped its recording speed during the write process.
- 20x HS-RW writing speed
The CR-485C TE is the first ever recorder that supports 20x writing speed with
blank HS-RW media. Keep the last sentence in your mind. The 20x (CLV) writing
speed is only valid with brand new HS-RW media. If you insert already used HS-RW
media, the maximum writing speed will be 12x. Even if you perform a full erase
you cannot have the 20x recording speed. Again the 20x (CLV) speed is not described
at the Orange Book, but Mitsumi engineers felt it can be accomplished with current
media/technology. Mitsumi calls this mode "SSW" (Super Speed Write).
For writing a full 74min task at this speed you will need 4:21mins:
Below it's the Nero CD Speed writing graph that illustrates the 20x Re-writing
The drive starts writing at 20x (CLV) the whole disc. Mitsumi CR-485E TE with
current firmware (1.0B) supports the following media for 12x and 20x. As you
can see almost all HS-RW media can be written at 20x, at least once:
Inside Nero, when a brand new blank HS-RW media is inserted, you will see the
20x recording speed under the writing tab:
- The package
The package supplied was the not the final European retail kit, but a special
test version. This included: the drive, a printed supported media list for CD-R/RW
media, 2 pieces of Verbatim's 4-10x HS-RW media and one piece of Hitachi-Maxell
80min 40x CD-R blank. The software supplied with the drive was Nero v18.104.22.168D,
InCD v3.82, EasyWrite and some additional utilities. The retail kit includes
2 years of warranty (only for Europe) and will cost €... including 16%
The front of the drive changed from previous drives and now contains only
the "HS-RW" logo and drive's features - "40x/20x/48x". You
will also find only one led, the eject buttons and the headphone input jack/volume
selector. Mitsumi has placed the 20x re-writing spec in the front of the drive,
which may be kind of confusing, since it works only with brand new HS-RW media:
At the back of the drive we will find the usual connectors (IDE interface,
power), the jumpers for setting the drive as a Master/Slave, the SPDIF output
connector and the analog/digital output connectors:
The Mitsumi CR-485C TE was installed as Master in the secondary IDE Bus, worked
under UDMA33 mode and DMA was activated automatically under WinXP. The drive
is a May 2002 model with firmware revision v1.0B installed.
