An outline is given of how advantages of conventional magnetic recording have been combined with those of compact disc technology to establish a method of high density magneto-optical recording, where information can be erased and freshly recorded at potentially very high superficial density and data rates. Application of the principles of thin film optics to the design of multilayer recording media with optimised magneto-optical "read" characteristics are emphasised, and possible future developments discussed.
