Abstract
The method to measure the apparent reflectivity with gloss meter is applied to the phase-change optical disks before and after initialization process. The apparent reflectivity measurements for relative large area and the reflectivity measured by optical pick-up are compared. The apparent reflectivity measurements are proven to enough for the characterization of recording layer. The measurement with gloss meter has several advantages of speed, simple structure, low price and etc.
