Problems solved by technology

However, due to the level of precision needed and the amount of data output required, the amount of area a single MEMS device could write to is relatively limited.
While each of these techniques has allowed the amount of storage to be increased, it has also increased manufacturing costs as well.

Embodiment Construction

[0017]Micro-electromechanical systems (MEMS) based storage systems that utilize a MEMS cantilever device are desirable due to their ability to store data at a high level of density, exceeding 1 terabit / in2. An exemplary embodiment of such a system is shown in FIG. 1 and FIG. 2. The individual MEMS cantilever device 10 includes a pair of cantilever arms 12 that are supported by a structure 14. The arms 12 are connected by a heater 16 that is coupled to a probe tip 18. The arms 12 and heater 16 cooperate to form a current path during operation.

[0018]The probe tip 18 is arranged adjacent to a polymer layer 20 that is formed on a substrate 22. The polymer layer 20 and substrate 22 forms a stationary storage medium 26 that is used to store data in the storage system. During a write operation, the probe tip 18 is heated by passing current through the arms 12 and into the heater 16. The heat generated by heater 16 is conducted into the probe tip 18 to a temperature sufficient to form inden...

Abstract

A method of storing data using data storage system having a positioning system for a micro-electromechanical system (“MEMS”) based data storage is provided. The method includes a moving MEMS-based scanner that interacts with a polymer medium to read, write and erase data. A first positioning system is coupled to the MEMS scanner to allow the storage of data over a defined area. A second positioning system is coupled to the first positioning system and the MEMS scanner to allow the use of a larger polymer medium. A plurality of storage modules is also provided to allow scalability of data storage.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 12 / 017791 entitled “Micro-electromechanical System Based Data Storage System” filed on Jan. 22, 2008, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to a micro-electromechanical system (MEMS) based data storage system, and in particular to MEMS based data storage systems having coarse and fine positioning arrangements.[0003]A MEMS based system can be utilized to generate nanometer-scale motion. Such systems can take advantage of this motion to build the capability of spanning micrometer-scale areas in an x-y plane. An important application of this type of system is in the area of atomic force microscopy (“AFM”) storage applications.[0004]In this application, a polymer medium is used for recording information with a MEMS scanner. Typically, the scanner includes an array of MEMS devices that...
