| Abstract | A large-scale read/write head model for perpendicular magnetic recording similar to that described in ref. 1 was constructed. The perpendicular field components between the head and image plane were measured and analyzed over a range of controlled direct currents in the main pole (N1) and saturable subcore (N2) coils. The fringing field profiles were found to have values between those of a probe head type and a nonsymmetrical thin film type. However, under certain conditions the field gradient in the gap region of this configuration can be significantly greater than that of a probe head. This is desirable to minimize record demagnetization. This type of head design combines the features of a probe head for writing and a ring head for reading. The flexibility of field profile control of this design also offers the possibility of using a large-scale version for particle perpendicular orientation. |

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.
