The following table contains my calculated values for various CD, DVD and BD parameters. I have not been able to verify the two parameters:

In Radius 23 mm
Out Raduis 58 mm

for a Blu Ray disk. Does anyone have a reference for these two paramaters?

Also, I believe the rest of the parameters and calculations are correct but would appreciate any feedback. I can give details of how I arrived at the calculated values as needed.
