Abstract
A magnetic tape using as recording medium selected magnetic or non-magnetic material is used for on-line physical and chemical analysis by exposure to selected external agents, physical or chemical, causing permanent alterations in the material, and changes in the magnetic properties of the materials are sensed to read out the recorded information in correlation with the analyzed phenomenon or process for storage, monitoring or control purposes.
