Magnetic storage, specifically in hard drives has advanced significantly since the first disk drive built in 1956 [1]. Interestingly enough, most of the changes thus far have been realized by scaling the components of a disk drive [1]. In recent years, the superparamagnetic limit has been seen as a possible limit to the rapid increase in hard drive capacities. Antiferromagnetically coupled (AFC...

Chemical data storage is inherently information inefficient, discarding many minor details to ease the burden of handling such data. The application of semantic web technologies and a triplestore allows the practical capture and referencing of a huge amount of metadata on each datum, thereby supplying the means to track authorship and veracity of properties within the database. This augments hi...

In this paper we address the important problem of data placement in tertiary storage taking object relationships into account. This work is in contrast to earlier schemes that either focus on specific data types or assume that data objects are accessed independently. Five new data placement schemes are developed. The effectiveness of these schemes is shown through simulation. The proposed schem...

The storage of patient and medical information in a disease registry is a critical concept for consideration during registry design and development. The choice of data storage methods may influence the ability to access data in the future; the ability to store data long-term; and the ability to exchange data with other registries or research projects as required. Additionally choosing a data st...

Although the basic idea may be traced back to the earlier X-ray diffraction studies of Sir W. L. Bragg, the holographic method as we know it was invented by D. Gabor in 1948 as a two-step lensless imaging technique to enhance the resolution of electron microscopy, for which he received the 1971 Nobel Prize in physics. The distinctive feature of holography is the recording of the object phase va...

The computing world is experiencing a transition from desktop PCs to connected information appliances, which — like the earlier transition from mainframes to PCs — will profoundly change the way information is used. The variety of devices capable of connecting to the Internet is astounding. Personal Data Assistants (PDAs), cellular phones, and even cars have Internet connectivity. Given the pro...

Fermilab, in collaboration with the DESY laboratory in Hamburg, Germany, has created a petabyte scale data storage infrastructure to meet the requirements of experiments to store and access large data sets. The Fermilab data storage infrastructure consists of the following major storage and data transfer components: Enstore mass storage system, DCache distributed data cache, ftp and Grid ftp fo...

NATIX is an efficient, native repository for storing, retrieving and managing XML documents. Other systems map XML data into structures maintainable by traditional DBMS. This introduces additional layers between the logical data and its physical storage, slowing down both updates and query processing. NATIX is native in the sense that it supports tree-structured objects like XML documents at lo...

We propose to develop a new method of information storage to replace magnetic hard disk drives and other instruments of secondary/backup data storage. The proposed method stores petabytes of user-data in a sugar cube (1 cm), and can read/write that information at hundreds of megabits/sec. Digital information is recorded and stored in the form of a long macromolecule consisting of at least two b...
