| Abstract | A study has been conducted to determine the variation of soft error rate, SER, as a function of the product between remanent magnetization and thickness, MrT, for thin film media with CoPtCr magnetic layers of three different compositions. Soft error rate as well as macromagnetic characteristics of the three sets of disks were analyzed. The soft error rate, measured at linear densities varying from 90 to 130 kBPI with a magnetoresistive head, showed a minimum for MrT values ranging between 0.6 and 0.7 memu/cm/sup 2/, depending on the alloy used. For values of MrT smaller than the ones mentioned above, the soft error rate quickly increased for all the magnetic layers examined because of very low coercivity, while for larger values of MrT the level of degradation, due to drop in resolution and poor overwrite, varied depending on the characteristics of the film. It was also found that, at linear densities approaching 130 kBPI the log SER improved up to 5 orders when high coercivity alloys were used, while at lower linear densities it was possible to obtain smaller error rates within a certain MrT range.< |

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.
