Memorex D² DVD±RW/DL Recorder - Page 18

For checking exactly what the Memorex F16 reports, we used three different media burned with other recorders. The media have been measured using the well known AudioDev SA300 DVD CATS system at 1X.

The drive is capable of reporting PI/PIF errors, so we will compare those measurements at various reading speeds:

• 3~8X CAV
• 2~6X CAV
• 4X CLV

Please note that the posted results are only valid for the specific tested Memorex F16 drive. Using other drives, even another F16, can produce totally different results. Be aware!

#2nd Test Disc - PISum8/PIF Comparison - 8X Reading speed

We can see that at the 8X reading speed, the PI error trend line rises up at the end. This is also what the SA300 system showed, even though the levels differ by a magnitude of 100. The PIF error trend line as reported by the F16 shows the same behavior as the SA300 system but again the levels differ.

#2nd Test Disc - PISum8/PIF Comparison - 6X Reading speed

The Memorex F16 used as a reader at 6X reports PI/PIF error levels that are much lower than CATS, leading the user to conclude that the disc is in top shape when in fact, that may not be the case.

#2nd Test Disc - PISum8/PIF Comparison - 4X Reading speed

The Memorex reported totaly different results in comparison to the SA300 with this disc. Neither the trend nor the values are the same.
