| Abstract | A write frequency has been increasing by improvement of a write driver and a write head for higher transfer rate in hard disk drives. A certain method for high write frequency operation is to put a write driver chip on the suspension. We designed a chip-on-cable-patterned suspension (C-CAPS) that is an integrated wireless suspension with a write driver chip on. This paper describes the first observation of the effect on the chip-on-suspension in the write frequency and what type of the C-CAPS is suitable, especially relating to the location of a chip, for high performance hard disk drives. Next, we clarify characteristics of the C-CAPS, such as write current transition time, interface between the chip and disk, shock resistance, frequency response, thermal deformation due to temperature increase of the chip, and static attitude change due to bonding the chip. We conclude the C-CAPS contributes to increase a write frequency and the best location of a chip is on the tip of the load beam for high performance hard disk drives. |

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.
