| Abstract | The authors use a dimensionless parameter Lambda ( Lambda ), defined as the ratio between lubricant thickness and average roughness (RMS), to optimize the tribological performance of the head/disk interface (HDI). Sputtered disks having a wide Lambda range (0.15-2.8) were tested for stiction, friction, glide, and contact-stop-start (CSS) performance. The difference in initial ambient stiction for various disks is negligible if Lambda <0.5, but is significant if lambda >0.5. In ambient and wet CSS, an optimal Lambda value is 0.57 for disks of 7.4 nm RMS roughness. Disks of low Lambda values show high stiction due to insufficient protection in ambient and more water absorption in high humidity environment. Disks of high Lambda values have larger stiction modulation due to thick lubricant. The dependence of stiction on Lambda agrees with the Li-Talke stiction model. The critical Lambda phenomenon can be used to explain other reported experimental results.< |

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.
