The number of the trade marks were lift up to 4, 2 of each type, to provide more information of how the drive treats discs of different trade marks. Below are the ATIP data of the discs tested.
The burn speed was the same for all trade marks and types of media. We also tested ability of the drive to record cyanine discs at the minimal speed, - this mode is usually used by audiophiles to get the highest quality sound. Formatting time min. CD-RW drive Formatting time min. Burn time min. If you don't want to download the utility, then here you can find the HTMl help file. In short, it measures quality of audio data extraction and of C2 error processing using a special test disc.
But in this case we couldn't measure C2 processing quality, and below are only general data on quality of audio track extraction. NEC ND - 10 min. But be careful when placing other devices close to it as they can burn. Vibration in case of unbalanced CDs The drive vibrated a little when worked with such discs but it finished reading them at a high speed and without errors.
Conclusion This drive can be recommended even for very demanding users. No grave flaws or problems were noticed. The impression is generally positive, though it burns CD-R and CD-RW too slowly, and I hope that its next versions will have it lifted it up to match the up-to-date level. Roman Shelepov srl ixbt. No registration needed! Smart Laser Drive Technology : The laser driver uses a pickup that incorporates a write strategy control circuit to ensure stable write performance.
Liquid Crystal Tilt Technology : The liquid crystal tilt mechanism provides accurate and reliable operation with discs that have been uneven curvature or thickness. This technology used during both reading and writing process. By taking a look at the front panel of the drive, we are seeing that is black while the loading tray is white. The originate of the drive is easily identified by the Memorex logo which is placed on the left side of the tray. After removing the screws we can see the drive's internal design, an action which of course voids the drive's warranty.
Clicking the follow image you can enlarge it for seeing the details. As we can see from the CD Speed results in the graph above both drives have approximately the same performance with the 80min pressed disc. The reported start reading speed was In the same task, the seek times for Teac are lower which means that is faster than Memorex. At the Random mode the difference wasn't very big but in the other two modes the 8ms difference is a considerable value.
Both drives needed the same time to finish the task , with reported average speed In the graph above we can see the seek time for all modes of both drives with an 80min CD-R media. Teac is again a little faster than Memorex but not with great differences. Ending the test we saw that the drives had similar performance results with a slight difference at the start speed which was End and average speed was almost the same.
By taking a look in the graph we can see that most of the red spikes are approximately at dB A. The reported average loudness error was The total score of the drive is Once again the drive performed very well, with the average loudness being at The error muting samples was The results that we took are reporting a good score of The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely.
Five tracks on the disc contain a sequence of progressively difficult tests. These tracks are referred as Check Level-1 through Check Level The files are reproduced played through a software multimedia player i.
Each level is considered as passed, if the tone coming out from the speakers is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested device. Each file was played 5 times. The fifth level includes an error size of 1.
That means that the drive has a perfect sound reproduction and an excellent error correction. The average error loudness was There were a few muted errors but none skipped.
The total test result of the drive is The average error loudness with the test disc was This time the C2 Accuracy with the Memorex drive is At the fifth level, which includes an error size of 1.
The drive has also a perfect sound reproduction and an excellent error correction as the previous drive. In the graph above we can see that the reported speed is almost the same for both of them in all modes. Teac is little faster than Memorex in all modes. In PTP the two layers are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, towards the outer range, for each layer.
Both drives use the same reading method and after the end of the test, as we can conclude from the photo above, the results we took are exactly the same. From the seek time test, which we can see at the graph above, Teac is faster than Memorex in the first two modes.
At full mode both drives have the same seek time. Teac DV-W50D managed to finish the reading test without encounter any problem. The drive read the scratched disc fast and at the end of the test the reported speed was 13X. So the upshot is a great ability. The data structure of the disc is exactly the same as the TDR, with the difference that there not scratches on it but defected areas with dimensions from 0.
There also fingerprints sized from 65 to 75 micrometers. Again the test was completed without any read errors. During the procedure the reading speed was reduced from 10X to 5X on the fingerprint defected area, but after that the speed resumed and the test was finished successfully. The reading procedure began with the speed of 3. At the end of the first layer the drive lower the speed in order to read the disc, an unreasonable event because the specific area wasn't defective.
Eventually the test was finished without any reported problems. The dimensions of the defected areas are ranged from 0. During the test the drive attribute smoothly without difficulties achieving the speed of 8X at the end of each layer. The reading process started at 3. The installation caused no problems. The drive needs no special drivers.
You can do just with the NeroBurning Rom; as for me, I used the latest version - 6. Nero Infotool tells what formats and disc types the drive supports: As you can see from the screenshot, this sample is RPC-1, however, according to the official site it's still the RPC-2 drive and you can't turn it into RPC-1 according to www. But you can solve this problem with the DVD Region free which provides the full regional protection.
Test results DVD recording The first media type to be tested is DVD-R as they are produced by much more companies and it often results in problems of recording. But first of all let's check drive's compatibility with discs from non-brand companies. Well, no such problems were revealed, and the drive successfully detects and burns most of them, in particular, 4x DVD-R from Princo.
Unfortunately, it doesn't support Digitex's discs yet. DVD-R burning Drive burning at 1x, min. Below you can see how the Lite-On drive handles the discs recorded. That is why all of them are read in a similar manner. Also note that it successfully works with multiborder DVD media. The number of the trade marks were lift up to 4, 2 of each type, to provide more information of how the drive treats discs of different trade marks.
Below is the ATIP for the discs tested. We also tested ability of the drive to record cyanine discs at the minimal speed, the mode usually used by audiophiles to get the highest quality sound. Read more about this technology here. But there are some disadvantages. First of all, such disc can be read only on a drive that supports this technology actually, only drives based on some Sanyo chipsets though they promised that soon all DVD-ROM drives will be able to read such discs after correcting the firmware.
Secondly, this technology requires high-quality CD-R media, and you should use either certified discs or try to record others at the lowest speed.
