25. Conclusion
In the following tests, we examined the DVD reading capabilities of the drive with scratched / defective DVD media. For the tests, we used CDVD Benchmark and Nero CDSpeed. The reference test media comes from ALMEDIO.
- Single Layer media
ABEX TDR-821
This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.
The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer rate test.
The drive managed to complete this error correction test without any problems and the reading speed, reached the maximum 16X at the end of the disc.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM of 4.7GB capacity. The data structure of the disc is exactly the same as that of the TDR-821, with the difference that there are no scratches on it but instead, defective areas of dimensions ranging from 0.5 to 1.1 mm.
There are also fingerprints sized between 65 and 75 micrometers.
Similar behavior to the previous test disc, with the drive again reaching its maximum reading speed of 16X.
- Dual Layer media
ABEX TDR-841
This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches of dimensions ranging from 0.4 to 3.0mm, on both layers.
No errors in this case either. Note also that the reading speed in this case goes up to 12X, which is the maximum supported speed for the DL media.
ABEX TDR-845
The disc is a single sided, dual layer DVD-ROM disc with a capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first includes defective areas and fingerprints.
The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.
ABEX TDV-541
The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity of 8.5GB.The disc is based upon the TDV-540 series which is designed for inspection and adjustment of DVD-VIDEO players. The disc checks the layer switch operation from layer 0 to layer 1 and also includes test pictures and test signals for DVD sound files.
The current TDV-541 also checks the error correcting capabilities of the drive and includes scratches from 0.4 to 3.0 mm.
The drive managed to complete the reading of this test media, with speed drops at the end of the first layer and continued with low reading speed during the second layer.
ABEX TDV-545
The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer DVD-VIDEO disc with a capacity of 8.5GB.
The TDV-545 includes artificial black dots on the data surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometer fingerprints.
This time, the reading was perfect without any speed drops. The dots and fingerprints were not a problem for the drive's error correction mechanism.
- Summary
Overall, good error correction mechanism, capable of reading over most defective areas.
