Devices and Methods for Storing Data

Description:

 

 

Background

The concept of storing data magnetically is used in most of the transactions such as credit cards, debit cards, identity cards etc. Many types of such cards and analogous devices include one or more strips of magnetic data-storage medium that can be read and processed as required in the course of the transaction. This form of data storage is aimed at providing some degree of security of the transaction, and also greatly increases the speed and number of transactions that can be executed, per unit time. One of the main disadvantage of these various conventional magnetically based data-storage techniques is that the data-storage capacity is limited, at least in part, as a result of the data being stored in binary form and also the data can be destroyed or at least corrupted, accidentally or deliberately. Due to these reasons, we found a new way to improve data storage device and methods.

 

Description

Our researchers at University of Nevada, Reno have created a data storage device that is a medium having at least two dimensions. Multiple data-containing loci are distributed on the surface. Each locus has a respective amount of magnetically responsive particles. The magnetically responsive particles in each locus can be selected from multiple selectable types, such that at least some of the loci have different types. The loci can be arranged so as to encode the data in a spatial manner for additional security. The data to be stored are distributed into multiple data units, wherein the data units are represented, at least in part, by a respective amount or number of magnetically responsive particles. Some of the data units have different respective numbers of particles. The loci typically range in size from the micrometer range to the nanometer range. The medium can be any of various configurations such as cards, sheets, films, etc.

 

Advantages

  • This data storage device and method allowing significant data storage capacity.
  • The data will not corrupt or destroyed easily with the help of our device and method.
  • Vulnerability of the data to theft or unscrupulous use will be reduced.
