Abstract

A fast access, major-minor, magnetic bubble memory is provided by defining a separate set of address minor loops in addition to the minor loops of a main storage area in which data is stored. A search operation is restricted to the address loops, selected data being read out of the main storage area only after the selected address is acquired.
