LiteON SOHW-1633S Recorder - Page 21

For checking exactly what the SOHW-1633S reports, we used three different media, burned with other recorders. The three media have been measured with 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 for various reading speeds:

• 3~8X CAV
• 2~6X CAV
• 4X CLV

Please note that the posted results are only valid for the specific tested LiteON SOHW-1633S drive. Using other drives, even another SOHW-1633S, can produce totally different results. Be aware!

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

The error values we observed with the SOHW-1633S were totally different from the error values obtained by the SA300 system. However, again, all graphs indicate increased error values at the end of the disc.

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

Much lower error levels were reported by the LiteON SOHW-1633S. The LiteON drive cannot produce error trend lines similar to those of the SA300 system, not even at 6X speed.

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

The LiteON SOHW-1633S continues to report lower error values than the SA300 system reports, even at 4X speed.
