CD-RW的功率校正:
Go the start of position of the test area of the PCA
Start recording random EFM with different writing power
Construct the modulation versus power curve m ( PW )
Derive the normalized parameter g
( g = slope = ( dm/m ) / ( dP/dPW ) )
Construct the g versus power curve g ( PW )
Determine Ptarget ( = PW at g target )
PWO = r * Ptarget
PEO = e * PWO
