CD-RW Roundup Vol 3 - Page
Which one is
After testing the majority of the drives in the 40x-recording platform, two
new drives from CyQve and Philips came in our labs. Both drives have the same
specs as many other drives in this category. We mainly focus on the writing
quality and the media compatibility the drives offer in the maximum speed, and
of course the overall performance against the competition.
- CyQve 4048
drive supports 40x writing (Z-CLV), 12x re-writing, has 2MB Buffer and includes
"JustLink" and "JustSpeed" technologies.
The exact writing speeds are 4x, 8x, 12x, 16x (CLV), 20x, 24x, 32x and 40x
(16-40x) (Z-CLV). The re-writing speeds are 4x, 10x and 12x (CLV). The maximum
reading speed is 48x (CAV). The drive supports all the known writing modes (DAO,
SAO, TAO and RAW), among with packet write/overburning option. There is no support
of the Mt. Rainier format.
- 40x writing speed
CyQve 4048 supports 40x writing speed using the Z-CLV writing technology. Below
is the Nero CD Speed writing graph which illustrates the use of Zone-CLV writing
The 40x writing speed range is divided into five zones: The drive starts writing
at 16x from lead-in till the 4mins, then shifts up to 20x until 10mins, shifts
to 24x at 14mins, jumps to 32x at 34mins and lastly shifts up to 40x at 56mins
and stays there until the end of the burning process. The theoretical average
recording speed is 29.24X with 80min discs, making it one of the slowest
- The package
package supplied contained: the drive, 1 piece of RICOH 80min 32x CD-R blank,
1 piece of CyQve 80min 4-12x HS-RW blank (unknown manufacturer 97m10s00f code),
audio cable and mounting screws. The software supplied with the drive was Nero
Burning ROM v184.108.40.206 and Ahead InCD v3.27 (for packet writing use). The package
also contains a printed manual for the drive and for Nero software. We must
also note the attractive design of the retail package! The retail package costs
around Euro 100.
On the front of the drive there are the "CyQve", "40x12x48",
"JustLink" and "High-Speed RW" logos. You will also find
one led, the eject button and the headphone input jack/volume selector:
In the rear panel of the drive we will find the usual connectors (IDE interface,
power), the jumpers for making the drive Master/Slave, the SPDIF output connector,
the analog/digital output connectors and 3 jumpers which are used to setup the
drive's working mode (UDMA33 or PIO-4Mode):
CyQve 4048 was installed as a Master in the secondary IDE BUS. The drive worked
in UDMA33 mode and after booting, identified itself as "CQ4048". We
used WinXP for the recording, reading tests and the DMA was automatically enabled.
The drive is a May 2002 model with firmware revision v1.01 installed. We used
the latest build of Nero (220.127.116.11), InCD (3.31), and CloneCD (18.104.22.168) for our
recording tests. The drive supports the 40x writing speed with all media when
you disable "JustSpeed". If you have this option enabled, the drive
will limit its maximum recording speed when the drive detects low quality media.
- Perfect Write Suite
offers a recording software with the "Perfect Write" name that can
be used only with CyQve 3248/4048 recorders to fine tuning the writing with
unknown media. It can test variable kinds of CD-R discs to figure out writing
parameters suit your drive such as optimal burning speed, laser power and so
on. Then user can save all the parameter settings for next time using.
Usually, the supported media list is stored in the drive's firmware. If the
disc you use is not on the list, the CD-RW drive will burn it with the default
parameters. This may cause writing error or writing break. If you want your
drive to extend its media supporting list, you must wait for new firmware to
upgrade. Right now "Perfect Write" can let you burn much more kinds
of media with your burner. However, this function only can go with special designed
hardware and firmware. Only the CD-RW drives, which support "Perfect Write",
can use this technology.
CyQve CQ 3248/4048 users can download this utility at ftp://ftp.met.com.tw/PW.In
order to use the "Perfect Write" software, you need the latest firmware.
After we finished the reading/recording tests, MET send us a newer firmware
version (v1.06) to demonstrate the use of "Perfect Write" Suite.
After we start the application, we choose the target drive (CyQve) in which
the adjustments will be applied.
We insert the media in the drive. The software informs us that the specific
disc is not supported, and allows us to start the adjusting process in order
to write the disc in the maximum allowed speed. We choose to proceed and the
media testing starts.
The application tests the ability of the drive to write/read in various speeds.
It starts writing a small region of the disc at 12x, reads it back at 12x, continues
the same test at 16x, and incrementally tests the 20x, 24x 32x and finally 40x
speeds. If the inserted media are determined for writing in a lower speed than
the maximum supported by the drive, the "PerfectWrite" will stop the
testing process in the maximum allowed writing speed. Have in mind that the
software does not simulate writing and reading, so the test disc cannot be used
more than once.
After the media testing, users should restart the PC and after restarting
the application, the software will prompt for applying the settings to the drive.
Our tests showed that after we applied the settings to the CyQve recorder,
we could select writing to the specific media brand in the highest speed indicated
by the "PerfectWrite", having the "JustSpeed" feature enabled.
