Research the part physics plays in the working of a dvd

Year 11 Physics Assignment: DVD Technology Nick Cooper Over the past decade the world has embraced a new technology called DVD. DVD is the next stage in optical storage technology and looks to update the manner in which digital information is stored for the future. The technology itself holds several key underlying physical principles which function in order to create DVD's superior performance and capabilities. Through current and recent research many developments have opened the door …

…physical processes which include refraction, polarisation, electromagnetic waves and wavelengths and many more factors, which all combine to create a very powerful and useful piece of technology. Such technology has come about thanks to research carried out through large trans-national corporations which have spent out immense amounts of money to develop these new ideas and equipment. As a result DVD promises greatly for now and the future in terms of large optical storage for everyone.
