| Abstract | High data rate recording is dependent on the speed of the write driver electronics and the intrinsic head response. The relationship between head response and head design is studied by finite element modeling. The primary parameters studied are head yoke length, head geometry, and number of coil turns. The head designs are tested using an experimental write driver with a 0.9 ns 10-90% risetime. The risetime of the driver is varied from 0.9 to 3.0 ns by adding capacitance at its output. The parametric and BER performance of three different head designs reveal a strong dependence of maximum data rate capability on the head efficiency and response. The best design showed low BER performance for writing to data rates slightly above 60 MB/s while reading at 15 MB/s with a PRML channel using a (0,4,4) run-length-limited code. |

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.
