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 and high data rate. The concept of data storage using this technique and the principles of operation (write, read and erase) are dealt with elaborately in this paper. A practical read channel model and its mathematical analysis are also presented. The evolution of the Millipede is described and technical specifications are provided. Moreover applications, challenges faced by the system and its advantages are discussed. The experimental data, mathematical equations and general figures have been borrowed by the authors to prepare the paper on the topic.
