Abstract
A magnetic bubble memory module according to this invention is so constructed that heat developed by a rotating magnetic field-generating coil assembly is transmitted to linear ferrite plates of a bias magnetic field-generating device very efficiently. Accordingly, the temperature rise of a magnetic bubble chip can be suppressed conspicuously. As a result, the service temperature range of the magnetic bubble memory can be expanded.
