For the test procedure we used three audio discs with different audio copy protections. The ripping process on all protected Audio discs was carried out with Exact Audio Copy v0.9 beta5. The tested protected Audio discs were:

Audio Discs	Protection
Celine Dion - New Day Has Come	Sony's Key2Audio
Natalie Imbruglia - White Lilies Island	Cactus Data Shield 200
Aiko Katsukino - The Love Letter	Cactus Data Shield 200.0.4 - 3.0 build 16a

The Cactus Data Shield 200 contains artificial errors that are not easily bypassed by the reader, while the Key2Audio contains a second session causing problems for readers when trying to read the Table Of Contents (TOC).

The Philips DVDR1648 recorder recognized up to the 12th Audio track of the CDS200 disc,

and with the "Retrieve Native TOC" option removed, the 13th Data track was also recognized.

The test results are shown in the following table:

Philips 1648	Key2Audio	CDS200
	Ripping process completed, EAC reports no problems, Read&Test CRC comparison successful for all tracks	Ripping process completed, EAC reports no problems, Read&Test CRC comparison successful for all tracks

With the Key2Audio discs and CDS200, EAC did not report any timing problems and at the same time, Read&Test CRC check comparison was the same for corresponding tracks.

- Cactus Data Shield 200.0.4 - 3.0 build 16a (Aiko Katsukino - The Love Letter)

This is a "special" CDS200 build, since it doesn't contain any artificial errors during the ripping process. Most problems occur when trying to write the ripped wav files, since the produced CD-R disc contains C2 and CU errors! This "problem" is rumored to be connected with specific chipset weaknesses.We ripped the disc contents with EAC and burned the wav file produced from the Cactus Data Shield 200.0.4 - 3.0 build 16a disc with the latest Nero version as AudioCD+CD-Text. The burned media was checked for C1/C2 errors and for BETA/Jitter errors with PlexTools software using Plextor PX-716A.

 

Philips 1648	CDS 200.0.4 - 3.0 build 16a
	Reading performed without any errors.

- C1C2 Error rate from PleXWriter PX-716A (8X CLV reading speed)

- BETA/Jitter Error rate from PleXWriter PX-716A

The C1/C2 error graphs show that the Philips 1648 drive managed to produce a 100% error free disc.

We then tried to extract all wav files with the Plextor PX-716A and PlexTools DAE Error Correction 5th Level enabled:

No errors were reported after extracting all files. The drive can backup the disc 100% accurately.
