| Abstract | The coupling dynamic between the focusing and tracking axis of a high speed optical disk drive system is exploited from the theoretical and experimental perspectives. By assuming the fact that the coupling dynamic is mainly due to the misalignment of the mass center and centroid of magnetic forces, a mathematical model of considered system is derived according to the first-principle method. Afterwards, experimental testings are carried out to identify some system coefficients and thereby verify the consistency of the theoretical model with practical system. The results turn out that the misalignment of mass center with centroid is not the only dominant reason for coupling, some other coupling mechanisms, such as stiffness coupling of the suspension wires, electro-magnet coupling and some nonlinearities in the system may also play some critical rule in the coupling dynamic. This analysis dedicates some deep insights of coupling phenomena for high speed disk drive, even though some phenomena could be roughly modeled by uncertainties insider the system. |

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.
