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

1 .INTRODUCTION

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 fundamental changes are ....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

Introduction
The millipede high-density data storage system is based on micromechanical (MEMS*) components borrowed from atomic force microscopy (AFM). Tiny depressions created with an AFM tip in a polymer medium represent stored data bits that can then be read back by the same tip. Data written in this way can also be erased using the same tip, and the polymer medium can be reused thousands of times. This thermomechanical storage technique is capable of achieving data densities exceeding 1 Tb/in , well beyond the expected limits of magne ....etc

Background
Magnetic and optical recording technologies are used for nonvolatile data storage. These technologies are reaching limit of data recording density of 500 Gb/in2 and 100 Gb/in2, respectively.

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
