Abstract

PURPOSE:To simplify confirming processing of the memory state at re-application of power supply, by reducing the bubble driving time at the disconnection of power supply. CONSTITUTION:In a control system for bubble memory using a bubble memory device of major/minor loop constitution, when the disconnection of a driving power supply is detected, the location of magnetic bubble train presented on a major loop 30 at that time is read with a major counter. The location is inserted between the gaps of magnetic bubble train on the major loop 30 as the major location information with a generator 17 to stop write-in/drive. At the restoration of the power supply, the location information on the major loop is detected with a repricator 16 and a detector 15, the information is erased, the magnetic bubble train on the major loop 30 with the detected major location information is stored in a minor loop 20 to restore the initial state.
