A motionless head 2-D parallel readout system for optical disks is presented. The system is designed to read data blocks encoded as 1-D Fourier holograms distributed radially on the disk active surface. Such systems offer several advantages: high data rates, low retrieval times, and simple implementation. It is used as the secondary storage of a high performance optoelectronic associative memory system.
