Abstract

With each new optical media product generation come rapid improvements in recording performance and density that require a reoptimization of disk parameters. One area of concern is optimization of the geometric design of tracking grooves and pre-formatted data on the disk substrate to support good seek performance in the drive. Guidance of design by scalar diffraction modeling supplemented with experimentally measured geometrical information has proven to be essential to the development of the highest quality optical disks.
