Abstract
A method of controlling a magnetic bubble memory device comprising a rotating field generation coil for applying the rotating field to a magnetic pattern formed on a magnetic bubble memory chip and transferring the magnetic bubble along the magnetic pattern. A bubble memory device controlled by the method of the present invention, is capable of operating in a wider ambient temperature range by heating the chip through heat generation realized by applying a heating current to the rotating field generation coil while the magnetic bubble transfer control is not carried out.
