摘要：

Based on new market opportunities for consumer electronics devices DataPlay has designed a new version small form-factor optical disc and drive featuring a capacity of 750MB per disc as compared to 500MB per disc of the original product. The NA of the optical pickup has been increased from 0.60 to 0.72. The track pitch of the media has been reduced from 0.74mum to 0.60mum, and the smallest mark size has been decreased from 435nm to 358nm. Details of the new design are presented as well as test results that show the higher capacity design is sufficiently robust to be used in consumer devices.
