  • Randall Victora, Kodak Research Laboratories, Rochester, NY, USA

This handbook brings together in a single volume expert contributions on the many aspects of MO data recording, including the materials in use, techniques for achieving recording function, and storage device subsystems. As a multiple author treatment, it brings perspective from many viewpoints and institutions. The insights delivered should be valuable to a wide audience from students to practitioners in all areas of information storage.
