A small form-factor 0.85NA red laser system with 1 GB capacity per 32 mm cartridge will be reviewed. Test results from write once media and newly developed first surface rewritable media will be shown. Modifications to the micro optical pickup (OPU) to use a high power laser diode to support rewritable media will be described, and results of thermal analysis of the complete drive system will be presented.
