| Abstract | Modern particulate tapes usually consist of a thin layer containing fine metal powder covering a nonmagnetic dummy layer. Because the MP layer is still relatively thick compared with what can be achieved with vacuum deposition techniques the excessive low frequency output can cause saturation in MR heads. Therefore, even thinner MP layers are desirable, but are more difficult to manufacture. Experimental tapes with soft-magnetic underlayers have been prepared with the aim of improving the frequency response. It has proved possible to suppress the long wavelength output by over 4 dB while at the same time improving the frequency response compared with the same thickness of MP on a conventional nonmagnetic underlayer. The incorporation of a soft-magnetic underlayer may therefore be an alternative to manufacturing extremely thin MP layers. |

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.
