DVD Error Correction Tests
In the following tests we examine 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 came from ALMEDIO.
- 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
The drive read the contents of the TDR-821 test disc without reporting any reading
errors or problems.
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 performance here as with the TDR-821 test disc, no errors or problems.
- 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.
The defective areas in this test disc were no match for the drives error
correction mechanism. Both layers completed successfully with nice, clean graphs.
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.
Once again the TS-H552U showed very good performance. The drive's error correction mechanism performed well with all four test discs, providing us with excellent graphs as seen above.
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.
Very good, if not excellent error correction in this case too, with a near perfect, smooth graph for both layers.
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 disc's surface, sized
from 0.4 to 1.0 mm. It also has 65 - 75 micrometer thickness, fingerprints.
Again in this case, great reading, indicating once again a great error correction
