| Abstract | The use of quadrilayer film structures can maximize the magnetooptic (MO) effect in reflected light used for readout in optical data storage. A computer program and a multifilm optical model have been utilized to search for optimized quadrilayer structures based on various figures of merit (FOMs), including differential MO signal, shot-noise-limited SNR, and SNR expressions arising from other noise sources. Selection among various FOMs allows tradeoffs relative to the magnitude of the reflectance or thermal efficiency in writing. Disks were fabricated on the basis of the simulation design rules, and experiments were conducted to assess the recording performance. The authors report on the optimization search used in the design program and the formation of the associated FOMs, and they present data on signal and noise to illustrate the value of the model.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
