Mitsumi CR-485FTE -
is the first manufacturer that decided to support the 54x CAV writing speed.
In a time frame where all the optical storage manufacturers announced their
52x writers, Mitsumi made a step forward by demonstrating the Mitsumi
CR-485FTE at CeBIT, Hanover 2003.
The specifications of the drive are impressive and include 32X Ultra High
Speed Reading and 54X CAV reading.
CR-485FTE features the ExacLink buffer underun protection, patented by Oak
most Mitsumi CD-RW writers, the CR-485FTE also supports the Aegis Write™ Shield.
This is a technology is developed by Mitsumi for optimizing and improving
the writing quality on a disc. In particular, this feature checks the quality
of the inserted media and automatically sets an upper writing speed
limit, to maintain a high writing
In addition, it automatically optimizes the Optical Power Calibration (OPC)
method and chooses the perfect writing strategy based on a comprehensive
data base. During writing, the Aegis Write monitors the process and automatically
optimizes it by setting the most appropriate speed. The laser
power is also adjusted accordingly, in order to offer the best
Mitsumi CR485FTE also features the SSW(PAT) (Super Speed Write(PAT)) technology,
which allows burning blank CD-RW's at high speeds.
As we already mentioned, the Mitsumi CR-485FTE drive offers 54x CAV CD-R
writing, 32x P-CAV US-RW rewriting and 54x CAV reading. The drive has a 2MB
which, combined with
the ExacLink technology, helps a user to avoid buffer underun problems.
The following pictures show all the supported writing / reading speeds by
The supported recording methods are the Track at Once (TAO), Disc at Once
(DAO), Raw DAO 96, multisession and packet writing. The support of recording
in the RAW mode with 96 out of 98 writable subchannel data, makes this drive
a good prospective protection copier.
The Mitsumi CR-485FTE is able to read CD-R/RW, Video CD, CD, CD-text and
is Mount Rainier compliant. Notice that the drive is not able to retrieve C2
error information, or at least not by using any of the known
to us MMC (Multimedia Command Set).
Below you can see the CAV writing strategy of the Mitsumi CR-485FTE, when
using 80min blank CD-R media:
The drive starts writing rather fast, at 24.69x and accelerates up to 54.07x,
giving an impressive average writing speed of 41.22x. The 54x CAV speed is
achieved at the address
80:00:00 (exact end of disc).
- The package
retail package includes the Mitsumi CD-RW drive, a multilingual quick start manual,
and an application software CD-ROM.
This CD-ROM includes Nero Burning Rom as the main CD recording/authoring
software and InCD for random access rewrite on CD-RW media (UDF packet writing
reading /writing under the Mount Rainier format.
In addition, it includes some arcade games for your spare time
and the MP3 JukeBox software, along with manuals and drivers for many Mitsumi
Last, in the retail package you can find the usual
internal audio cable, an IDE cable and mounting screws.
The front panel of the drive looks rather simple. On the disc loading
tray you can see
the "HSRW" logos.
The eject button is placed below the tray, on the right side of the front panel,
The indication LED lights up orange, when a CD is loaded in the
drive. It blinks green, as long as the CD is being read. If there is no CD
in the drive, the LED does not light up, even if the device has been switched
on. The LED lights up red during writing. In case an unsuitable CD has been
inserted in the drive, or a hardware or other error has occurred, the LED
starts to blink.
The drive has also a headphone socket where headphones or mini loudspeakers
can be connected here to play audio CD's. A volume control button, for
adjusting the volume for audio CD's, is also available.
On the rear of the drive you have the usual IDE interface, power connection
and analogue audio output connectors.
Let's have a look at the internal of the drive. Please avoid opening
your Mitsumi, since it will make the drive's warranty invalid. After removing
the screws at the bottom we can see the drive's internal design. The basic
chipset is developed by OAK Technologies.
The Mitsumi drive was identified as "MITSUMI CR-48XFTE" 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 4.0c installed, but the tests were
done with a newer 7.0c version we flashed ourselves.
In order to have a better picture of the drive's performance, in the following
pages we include the benchmark results
of both Optorite CW5201
and Plextor Premium, both obtained during our latest hardware review.
