| Abstract | The effect of naturally adsorbed gas on an NiP-Al substrate surface on the growth of a very thin WCr seedlayer and the effect of growth form of a WCr seedlayer on the microstructure and properties of magnetic recording media have been studied. An Auger electron spectroscopy analysis result clarifies that the critical thickness at which the WCr seedlayer changes from island-like to continuous layer is 2.5 and 1.5 nm when grown on the substrate surface with and without naturally adsorbed gas, respectively. The result means that the NiP-Al substrate surface with adsorbed gas enhances the island-like growth of the WCr seedlayer, probably due to the reduction of mobility of sputtered WCr particles when they react with the adsorbed gas on a substrate surface. It is found that the media grain size and the media noise are reduced only when using a WCr seedlayer thinner than 1.25 nm fabricated on substrate surface with adsorbed gas. |

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.
