Some File Structure Considerations Pertaining to Magnetic Bubble Memory
William E. Wright · The Computer Journal · 1983
Several aspects of file structures are considered with respect to magnetic bubble memory architecture. Topics discussed include record sizes, wrap-around, parallel and serial systems, blocking, tree structured files, indexed sequential files, and hashed files. Primary attention is given to minimizing access times. Various file structures are identified for which the nature or extent of utilization is significantly different for magnetic bubble memories than for rotating disks or drums. Some structures are shown to be suitable or unsuitable for magnetic bubble memories. Tendencies of structure parameters to be bigger or smaller for magnetic bubble memories are shown.
