| Abstract | A thin film inductive write head suitable for 10 Gbit/in/sup 2/ recording density is simulated using boundary element modeling. The material was assumed to have the non-linear B-H properties of FeAlN-SiO/sub 2/ multilayers-an initial permeability of 3400 and saturation flux density of 1.9 Tesla. The simulations show that with a trackpitch of 1 /spl mu/m and a gap of 0.18 /spl mu/m, it is necessary to use trimmed poles and a trackwidth of 0.6 /spl mu/m to achieve a written trackwidth of 0.8 /spl mu/m and allow for an erased-band of 0.05 /spl mu/m at each track edge. This allows 0.1 /spl mu/m for track misregistration, which is within tolerance achieved by current optical servos. If focused ion beam etching is used to trim the poles from the air bearing surface (ABS), to prevent fields from the etched shoulders from disturbing data in adjacent tracks, the shoulders should be etched 0.5 to 1.0 /spl mu/m from the ABS.< |

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.
