In addition, they've defined a new "mechanical property index" for unburned discs. This is an attempt to separate the influence of media and burning strategy. Again, they've defined a weighted quality index based on the following basic measurements:

- AxialN CAV (axial deviations at 3000 rpm CAV, < 1 micron)
- Radial CAV (radial tracking errors at 3000 rpm CAV, < 40 nm)
- RRO (Radial Run Out at 1x CLV, < 70 micron)
- Push-Pull signal (1x CLV, laser tracking- deviation of min/max < 15%)

Because this is a European test, some media will not be available elsewhere and some brands will have different suppliers. In particular, the European manufacturers do not have as close contact with the hardware manufacturers as do Japanese, Korean or Taiwanwese producers. As a result, the firmware of many drives may not have appropriate strategies implemented and fall back to conservative "generic" strategies.

European manufacturers:

- 3A Media, Austria, works closely with Plasmon, Ciba dye

- Skymedia, Switzerland

- MAM-E, France (former Mitsui, now in CSI concern)

- Sony (manufactured in Salzburg, Austria)

The Ritek discs were ordered from an online supplier as a "no-name" source to check on quality fluctuations.

The Skymedia discs were essentially unuseable, Prodisc and Ritek positive surprises. The BenQ managed the most useable 8x burns.
