Abstract

Dynamic GaAlAs diode laser marking experiments on an optical data storage medium are reported. The medium comprises thin films of a proprietary organic recording layer that are spin coated onto both glass and plastic disk substrates. These amorphous films with high substrate incident reflectivities (R - 30%) are stable to both air and moisture. Writing experiments were performed in the substrate incident mode. Readable marks were made with 2 to 15mW of laser power at pulse widths down to 50 ns. The marks are pits with well-defined rims. The dependence of laser recording quality on both disk and marking parameters will be discussed.
