Abstract

Lens designs are developed for parallel readout of data stored on optical disks. Optimizations of a single aspheric objective with standard wavelengths and numerical apertures are performed. These designs are evaluated for degree of parallelism achieved, improvement in aggregate data rate, source power requirements, and effect on head mass. We find that more than 225 channels and data rates of 4 Gbits/s can be supported with low-cost readout optics.
