ABSTRACT:
An improved reflective silver laser recording and data storage medium for direct read after writing, having a protective gold plating on the silver particles of the reflective surface. The gold plating increases the recording sensitivity resulting in higher contrast ratios for the recorded data. Increased contrast ratios between recorded and non-recorded reflective areas are obtained by the gold plating allowing lower laser energy for readout of recorded data. The reflective silver surface is plated with gold by an electroless ion displacement procedure.
