The following new components have been developed for magnetic tape recording: the matrix writing head, which allows fine track pitch and high integration (1,024 tracks) at reasonable cost, and the Kerr reading head, which takes advantage of optics for high sensitivity, parallelism, and easy tracking. The feasibility of reaching a data rate in the range of 40 megabytes per second and a density of up to 2500 tracks per inch (TPI), 50 kilo flux changes per inch (KFCI) on half-inch tape has been demonstrated.<>

The expansion of multimedia networks and systems depends on real-time support for media streams and interactive multimedia services. Multimedia data are essentially continuous, heterogeneous, and isochronous, three characteristics with strong real-time implications when combined. At the same time, some multimedia services, like video-on-demand or distributed simulation, are real-time applications with sophisticated temporal functionalities in their user interface. We analyze the main problems in building such real-time multimedia systems, and we discuss-under an architectural prospect-some technological solutions especially those regarding determinism and efficient synchronization in the storage, processing, and communication of audio and video data.<>

Powerful but nevertheless easy-to-operate systems for backing up and reconstructing data from clients are necessary in a distributed heterogeneous environment. The concept of the Siemens Nixdorf Informationssysteme (SNI) AG is based on a client/server model. It runs under the control of a SINIX server and includes backup clients for various Unix systems, PCs such as those with MS-DOS/Windows, and PCs in the Novell NetWare network. Logical data backup and restore actions for any file or disk partition in a Unix system and for any file in a PC system can be performed automatically and at defined times during an operation. The backup media are tapes, DAT cartridges, magneto-optical disks, and associated autochangers and jukeboxes.<>

Digital audio and video are difficult to store and replay due to their real-time nature, high bandwidth, and large size. To investigate the techniques required to support audio and video, a specialized continuous media storage server, in operation since December 1991, was built at Lancaster. This server and the techniques used in its design are briefly described. The current work at Lancaster in distributed continuous media storage servers is then outlined. This work is developing a scalable multimedia storage server architecture that supports wide area multimedia storage; storage server scalability that allows the incremental addition of new nodes; high bandwidth through the use of load balancing, including node striping and file replication; and store-and-forward caching for slower and faster than real-time links. The architecture will allow tens of simultaneous users for classroom teaching and video-on-demand applications.<>

The National Storage Industry Consortium (NSIC), an organization of universities and industrial companies involved in the field of data and image storage, has established the National Storage System Foundation (NSSF). NSIC/NSSF was organized to promote the development of high-performance, interoperable digital libraries to serve as repositories for national information assets. NSIC/NSSF has an inclusive organizational philosophy allowing any number of members with the same technology and product interests. It is open to universities, companies, and governmental agencies and laboratories. The general requirements for membership of a company in NSIC are that the company: engage in the development, manufacture, integration, and/or use of storage systems or components; perform a substantial portion of its storage research and development activities within the United States; and be eligible to receive United States federal research and development funds.<>

Multimedia interfaces increase the need for large image databases, supporting the capability of storing and fetching streams of data with strict synchronicity and isochronicity requirements. In order to fulfill these requirements, the GigaView parallel image server architecture relies on arrays of intelligent disk nodes, with each disk node being composed of one processor and one disk. This paper analyzes, through simulation, the real-time behavior of the GigaView in terms of delay and delay jitter. For a high-end GigaView architecture, consisting of 16 disks and T9000 transputers, we evaluate stream frame access times under various parameters, such as load factors, frame size, stream throughput, and synchronicity requirements.<>

The requirements for data storage and management in experimental high-energy physics (HEP) are examined. Current and future needs for storage and access to data are presented briefly from both technical and sociological standpoints. Questions such as "file management or database management?" and "distributed or centralized data management?" are of vital interest to HEP and probably to other disciplines and businesses. These questions are discussed but inevitably are not fully answered.<>
