We developed a new technology for writing and reading a tape which shows good perspectives for very high track density recording. The key elements of this new technology are:-parallel recording of a large number of tracks thanks to a matrix head structure creates macro tracks which are significantly wider than the guardband separating adjacent macrotracks,-optical detection of the magnetic flux flowing in the reading core thanks to Kerr effect allows high transverse resolution and precise track following,-parallel readout of adjacents bits allows efficient electronic crosstalk compensation,-serpentine structure, allows recording of a very large number of tracks on wide tape without requiring stringent precision on tape stability and mechanical positioning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
