7.5.1
ALFA MEASUREMENT CIRCUIT FOR RUNNING OPC
The task of the ALFA block is to measure the parameter ALFA for use as an error signal in the running-OPC control loop
of a dye or phase change writer. The two media types require different alfa measurement methods. For dye media the
decrease in pulse area of the returning signal during a write pulse is taken (‘absorption measurement’), for phase change
media the laser power incident on the recording layer is used, which is also derived from the returning signal (‘reflection
measurement’). For both media types two methods for alfa measurement are implemented, which are defined in
Sections 7.5.2 and 7.5.3. Selection of the 4 possible ALFA methods is done by bits PC/DYE (phase change or dye
media) and ALF1/2 (first or second method), see Fig.16.
