Abstract
In a heating and temperature control system for a data storage apparatus comprising at least one matrix-addressable ferroelectric or electret memory device, Joule heating means are provided in the memory device, a temperature determining means is connected with controller circuitry and the controller circuitry is connected with an external power supply, which controlled by the former powers the Joule heating means to achieve a selected operating temperature. In a method for operating the heating and temperature control system an ambient or instant temperature of the memory device is determined and compared with the set nominal optimal temperature, and the difference between these temperatures is used in a predefined algorithm for establishing control parameters for the application of power to the Joule heating means to achieve the selected operating temperature in the memory device during an addressing operation thereto.
