| Abstract | Actuators for objective lens positioning are indispensable components for writing and reading data to and from optical storage media. Significant advances in the technical capabilities of microlens actuators for optical heads have been achieved using MEMS technology, enabling miniaturisation and integration of optical data storage systems. In this reported work, a compact silicon-on-glass (SOG) actuator for two-dimensional (2D) positioning of a dispensed polymer microlens is developed by MEMS technology. A wafer-level process for fabrication of the SOG actuator is achieved using anodic bonding, in which a Pyrex wafer was bonded with an ultra-thin silicon wafer. Dispensed polymer microlenses are fabricated and subsequently integrated onto the 2D actuator by an automatic handling system. Typical displacements of about ±28.6 μm in the tracking direction and 3.2 μm in the focusing direction are experimentally characterised. The compact 2D SOG actuator and assembly technology may be particularly useful for expanding the application area for the optical head. |

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.
