1. INTRODUCTION
Today data storage is dominated by the use of magnetic disks. Storage densities of about more than 5 Gb/cmhave been achieved. In the past 40 years areal density has increased by 6 orders of magnitude. But there is a physical limit. It has been predicted that superparamagnetic effects- the bit size at which stored information become volatile as a function of time- will limit the densities of current longitudinal recording media to about 15.5 Gb/cm2.In the near future century nanometer scale will pre ....etc

In this seminars, we examine the feasibility of using thin-film NiTi shape-memory alloys (SMAs) for thermomechanical data storage as an alternative to the polymer thin film used as the data storage medium in the IBM Millipede device.'8' NiTi is a potentially more robust and rapid storage medium than the polymer films currently used for thermomechanical data stor age. For example, the poly(methyl methacrylate) (PMMA) medium ....etc

Abstract

This paper focuses on the field of nano memory storage systems. It in particular discusses about a research project named Millipede under development at IBM labs.
In this, nanometer-sharp tips are used to scan the storage surface and to write and read data. In this, storage densities of up to 500 Gbit/in2 can be achieved by thermo mechanical writing and reading using probe tips. This concept combines ultrahigh density, gigabit capacity a ....etc

thermomechanical data storage ppt

Abstract
In the 21st century, the nanometer will very likely play a role similar to the one played by the micrometer in the 20th century The nanometer scale will presumably pervade the field of data storage. In magnetic storage today, there is no clear-cut way to achieve the nanometer scale in all three dimensions. The basis for storage in the 21st century might still be magnetism.

Within a few years, however, magnetic storage technology will arrive at a stage of its exciting and successful evolution at which ....etc

THERMOMECHANICAL ANALYSIS



INTRODUCTION

Thermomechanical Analysis (TMA) is the study of the relationships between a sample s length (volume) and its temperature
Thermal expansivity () is a useful engineering quantity

DEFINITION

A technique in which a deformation of the sample under non-oscillating stress is monitored against time or temperature while the temperature of the sample, in a specified atmosphere, is programmed.

PRINCIPLE

A cylindrical or ....etc

ABSTRACT
In the future, the current method of magnetically storing data may reach its limit of maximum achievable density. Hence we need a data storage technology which has high storage capacity and is small in size. The solution is Thermomechanical data storage. Thermomechanical Data Storage is a data storage scheme in which nanometer sized pits on a plastic disc represent digital data. This data storage concept combines ultrahigh density, terabit capacity, small form factor and high data rates. By using this concept, we w ....etc
