Apparatus for producing optically and magnetically discernible prints of information has an endless magnetic recording medium for providing an erasable magnetic record of the information in response to thermal gradients and an endless transducer medium for providing electrical gradients representative of the information. An electrical energy supply enables the electrical gradients to provide thermal gradients producing the erasable magnetic record. This magnetic record is printed out with a magnetic toning agent and is thereafter erased.
