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

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

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

INTRODUCTION

Recently, there have been rapid developments in the field of information technology, resulting in the need to generate, store, and transport a large amount of information while ensuring data security, an important issue in today's digital age. To meet future demands in information technology, femtosecond laser pulse processing offers a powerful tool for developing new high-capacity devices because it allows fabrication of three-dimensional (3-D) structures inside a wide range of transparent materials. In particular, multilayered ....etc

3D optical data storage is the term given to any form of optical data storage in which information can be recorded and/or read with three-dimensional resolution (as opposed to the two-dimensional resolution afforded, for example, by CD).

This innovation has the potential to provide petabyte-level mass storage on DVD-sized discs (120mm). Data recording and readback are achieved by focusing lasers within the medium. However, because of the volumetric nature of the data structure, the laser light must travel through other data points befo ....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
