| Abstract | We have developed an analysis method that uses spinstand tester to estimate magnetic cluster size distributions, including average size and size deviations. To statistically analyze the alternating current (ac)-erased magnetization distribution, the autocorrelation functions of the magnetization distributions were derived from readback media noise spectra. The cluster size distributions were quantified from the autocorrelation function by utilizing the undershoot value as well as the zero-crossing shift length. Good agreement with minor-loop analysis supported the validity of this method. This method will be useful for developing media because measuring is easy, fast, and can be used for various kinds of recording media under a variety of conditions. The relationship between the transition jitter and the magnetic cluster size distributions were clarified by regression analysis. The results showed reducing the average cluster size should be the first priority, and lowering size deviation should be the second. |

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.
