CDR burn speed, why does it make a dif

[nsdn]

I have tryed to search or this but....alas I can't find a answer.

I generally buy stacks of Datastream media which to date have worked flawlessly in my trusty old 6* ricoh burner. Then the last stack I bought would not burn for some reason...they looked slightly differant....

Anyway to cut a long story short...firned offered me a SonyCRX-175A1 for 30 AUD, which is a 24* burner.

Question is when I burn at 24* my dvd player skips and farts and carried on, but the disk plays in my computer no probs, but if I slow the burn process to 12 x which is as slow as the burner can go it plays fine on my stand alone DVD player.

Why is this so? I know the writer does a power calibration before it starts burning, at higher speed, the lazer diode must be burning at a higher intensity, so why does it burn better at lower speed.

It is annoying because if i could burn at 24 times....I could make a disk in 3 or 4 minutes...but now i am only twice as fast as I was before...(

The reason it burns "better" at lower speeds is often due to small problems in the media itself. The media may be slightly imbalanced, and when burned at lower speed, these imperfections may not be a problem, but when the disc is sped up, it can wobble causing data problems.

also, the laser takes a certain amount of time to turn on and off. during the time that the laser is turning on and off, the disc moves.

this causes the marks burnt onto the disc to be less sharp the faster the disc is spinning... instead of something like |_| u get \_/. the second on is what u want to avoid. u want nice sharp edges so that the reader has no difficulty in reading the disc.
