Abstract

We demonstrate experimentally, for the first time, erasable magneto-optic recording on an optical disk containing multiple data layers. This technology is based on the use of multiple, partially transmissive data layers separated by spacer regions. It takes advantage of the narrow depth of focus provided by the objective lens to allow selective access to data on each layer by moving the focal position of the objective lens.
