Paper Abstract

The sensitivity functions (laser marking efficiency) of 10 write once read many times (WORM) optical memory media have been analyzed. All WORM media are found to fall into two classes of behavior: the first class has a behavior linear in 1/X, where X is related to the incident energy or fluence, and the second class behaves according to a Fermi-Dirac function. These expressions of the laser marking efficiency can be used to model the WORM read/write channel for all settings controlled by an optical drive.
