Abstract:

A motionless head 2-D parallel readout system for optical disks is presented. Its unique features are discussed and it is compared to various parallel access optical storage media. The motionless-head parallel read-out system for optical disks is shown to meet current and near-term future requirements for high performance secondary storage. In order to select a memory architecture compatible with the motionless-head disk, inner-product and outer- product associative memory algorithms are compared in terms of their storage requirements, search times, system complexities, and fault tolerance. Based on this comparison, the page serial, bit-parallel inner-product method is shown to be well suited to implementation with parallel readout optical disk, and opto- electronic XNOR gate arrays, using for instance the SiPLZT technology. Finally, the associative memory system design is presented.... Memory, Associative memory, Optical disks.
