- Single Layer media
This is a single sided, single layer DVD-ROM with 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.
Excellent performance. The graph is smooth, even at 16X.
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.
Good behaviour, however the drive dropped speed once, just before the start of the second defective region, in order to read the contents of the disc successfully. No errors reported.
- Dual Layer media
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.
Reading was very good with the first layer. In the second layer, at the end of the defects area the drive dropped its reading speed. Fortunately no errors were reported and the process finished successfully.ABEX TDR-845
This test 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 discs is that the first includes defective areas and fingerprints. The dimensions of the defective areas ranges from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.
Very good performance despite some minor speed falls.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 on 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.
This is supposed to be a difficult disc for many drives. The Sony drive however, managed to read it successfully.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.
Excellent, smooth graph.- Conclusion
Generally, DVD error correction on the Sony drive is very good.
