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 comes from ALMEDIO.- Single Layer media
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 ED16DVDR read the disc successfully but the speed graph is a little messy. The reading speed is low and there are too many speed changes which indicates that the drive can take a long time to read a defective disc of this nature.
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.
Again, the same characteristic performance. The disc was read without reporting errors but with a lot of speed changes.
- 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 once again forced the drive to change speed.
The disc is a single sided, dual layer DVD-ROM disc of 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 micro meters.
Ditto. With all the ABEX test discs, the drive did not produce any errors, but it did exhibit a rather strange behaviour reading at the full range of speeds between 4X and 5X which produce the yellow strip across the surface from start to finish, meaning that it wasn't only limited to the areas with defects. This could be indicative of a very good if slow reader for defective discs.
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 a nice clean output and the Philips drive just ignored the defective area...
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.
The ED16DVDR showed excellent behavior with TDV-545 test disc. Linear, smooth graph means very good performance.
