We give a simple model for interferences occurring in 2-D patterned media for magnetic recording. We investigate some constraints induced from the model. We also give an encoding algorithm for the constraints which works well with minor exceptions.

The technology and cost barrier of the SSD motivated many research groups and companies to merge the SSD with low cost and large capacity storage device, Hard Disk Drive (HDD). As the NAND flash memory technology is getting more advanced, price of NAND flash memory dropped dramatically. As number of bits per cell in NAND flash memory is increasing, the price of $/GByte is reduced. This trend wi...

In this paper, we present RDLS (Rich Data Location Services), a grid middleware for data management designed to meet the requirements posed by the GREDIA project [1]. The main purpose of the described Middleware components is to provide the prerequisite services for storage, search and retrieval of annotated, rich media content in a large-scale distributed environment. These services can be eff...

The long life and low usage of archival data make cost considerations paramount. Today, most archival storage architectures depend on magnetic or optical media such as tape and disk because they have a low initial cost per byte. The high initial cost of storage class memories (SCMs) has been seen as prohibitive for archival use. Nevertheless, SCMs have many advantages for archival use, includin...

This exploratory study examined the health record retention practices among health information management professionals in acute care general hospitals in the United States. A descriptive research design was used, and data were collected using a self-reporting survey. Respondents answered questions about the relationship between researcher-assigned storage media profiles (descriptions of the ty...

This letter presents an experimental study that shows that a 3(rd) physical dimension may be used to further increase information packing density in magnetic storage devices. We demonstrate the feasibility of at least quadrupling the magnetic states of magnetic-based data storage devices by recording and reading information from nanopillars with three magnetically-decoupled layers. Magneto-opti...

Bacillus subtilis strain 5230 endospores suspended in a variety of suspending media at a concentration of ca. 10(8) per ml were heated at 95 and 75 C. The effect of the heating at 75 C was measured by plate count, and was reported as the heat-activated decimal fraction of the total viable-spore population. Thermal inactivation at 95 C was influenced by the suspending medium. No effects on heat ...

In data dominated applications, like multi-media and telecom, data storage and transfers are the most important factors in terms of power, area and system performance. Several steps which optimize these costs are present in our systematic Data Transfer and Storage Exploration (DTSE) methodology. Here, we focus on the Storage Cycle Budget Distribution (SCBD), a step which is crucial for meeting ...

M anufacturers commonly use tags or markers to authenticate and identify commercial products. Some typical applications for authenticating a prod-uct's source include visual holograms on software packaging, fluorescent spectrally encoded fibers in a garment's brand label, and hidden microscopic brand marking of aerospace parts. Applications that identify products, either individually or within ...

Conventional wisdom holds that reducing disk latency leads to higher disk utilization, maximizing disk utilization leads to higher throughput, and employing a faster disk leads to better performance. All of this is true when building a conventional le or database system. In this paper we show that these principles can be misleading when applied to a media server. To design such a server, we pro...
