Re: [ARSCLIST] CD writing speed

[Bob Olhsson <olh@xxxxxxxxxxxxx>]

There's another issue which is reflectance, the potential signal to noise ratio available for playback.

My understanding is that reflectance is reduced as write speed increases. Better reflectance makes for more stable playback on ordinary CD players. Obviously there is a point of diminishing returns where the poorer error rates cause bigger problems.

Poor reflectance can increase the amount of servo activity. In many player designs this will heat up the main crystal which is located on the motor control chip and actually affect the sound by altering the playback speed and stability. The engineers at Phillips suspect this common player fault is where the mysticism around green pens, 1x burning, etc. has an actual technical basis. Of course sounding a bit different has nothing at all to do with sounding better or more accurate.
