Proposal of an alternative technique for high density data storage

Abstract

An alternative technique is proposed and discussed for ultra-high areal density data storage. The proposed data storage system consists of a ferroelectric medium and the corresponding writer and reader for writing the data to and reading the data from the disk medium. Comparing to the existing magnetic data storage systems, the new recording system features simplicity in writer design and fabrication and a large output signal from the read sensor. The adoption of a perpendicular recording scheme also makes it more promising for future high-density recording applications. Its other advantages and drawbacks are also discussed based on an preliminary analysis on the writing and reading processes.
