Hard Disk Drive as a Magnetomechanical Logic Device

TL;DR

This paper explores the potential of using a hard disk drive as a magnetomechanical logic device by superimposing binary data and performing logic operations through magnetic field manipulation, expanding the functionality of magnetic storage.

Contribution

It introduces a novel approach to perform logic operations directly on magnetic storage media by superimposing binary states, demonstrating basic logic gates on a hard disk medium.

Findings

Successfully demonstrated OR, AND, XOR, and NOT operations on magnetic media.

Achieved three-state magnetization for superimposed binary data.

Proposed modifications to recording devices for logic operations.

Abstract

We consider the conditions how two binary numbers can be superimposed on the same track with the use of different recording magnetic fields. As a result the average magnetization of longitudinal medium along the track can have three states: -M, 0 and +M. Possibility to perform logic operations with these states is considered. We demonstrate OR, AND, XOR and NOT operations and discuss a modification of a recording device.
