Philips has demonstrated the world's first fully functional miniature optical disc drive using blue laser technology. Up to 1 Gbyte of data can be stored on a single-sided optical disc of just 3 cm in diameter, matching the size constraints of portable devices such as digital cameras, mobile phones, PDAs and portable Internet devices. This prototype illustrates Philips' leadership in optical storage technology, which is driven by superb media robustness and the low cost per Mbyte of the storage medium, making it optimally suited for large-scale distribution of pre-recorded content.
