The goal of this project is to determine the maximum "recording density" for storing digitized information using a grid of bar magnets. You'll learn about how information is digitized, and how the digitized information is stored magnetically. The project helps you to understand the limitations on information density recorded on magnetic materials.
Today, magnetic disk drives are used to store and retrieve information for many different applications. Digital video recorders (DVRs), MP3 players, and gaming systems are all examples of popular products that use a disk drive to store and retrieve information. Some other applications that you may not be familiar with are global positioning systems (GPS), banking systems, and automobiles.
