  • Patent number: 3980818
    Abstract: A recorder and reproducer system is disclosed wherein video or other information is recorded by modulated laser lattice ablation of an information storage medium on or a part of a record member. A high resolution microscope objective recording head is guided in a direction across the record by a needle tracking groove while a scanning laser beam sweeps the land adjacent the groove in one of a variety of rasters. The high density stored information is read out through the microscope objective by a television type camera or flying spot scanner while the reproducing head traverses the record with high resolution tracking. A lens mosaic is utilized to facilitate high density information storage and a binary ceramic lattic shutter array provides a binary coded address system for identificaton and retrieval of information stored on the record.
