Human Read - Machine Read Microfilm Mass Memory System.

Abstract

Abstract : The Human Readable/Machine Readable (HRMR) Microfilm Mass Memory System is an information storage and retrieval system for machine readable digital data and human readable microimages. The systemn is designed to record, via laser, both human readable microimages and machine readable binary data on nominal 105mm by 148mm film chips. Each film chip provides the storage capacity for up to 98 human readable microimages or thirty million binary bits. The system provides on-line automated storage and retrieval of film chips. This is achieved by the storage and retrieval unit which provides the capacity to store 6,750 film chips (containing a total of 2 times 10 to the 11th poweer bits of binary data). Under computer control, it is designed to provide rapid, random access to these film chips and on-line readout of the machine readable data recorded on any chip.
