What I mean is... take for example, you are downloading a movie that if from one person. As you are downloading it goes into your computer. By law of conservation of mass, nothing can be created or destroyed. Did we not just create a duplicate of a movie, for he has a movie and now I do. Other questions include the effects of Wi Fi wireless internet these waves of bit and information fly into our computers other computers constantly sending information.... where is this all coming from. Is this created? When something gets dumped and deleted from the Recycling Bin where does it exactly go? Back into the air in the form of heat... entropy?
 
You have to realize that everything on the computer is just binary code, 1 and 0. When you delete something in the recycling bin, those 1s and 0s that represented it are changed around so they no longer represent that program.
 
In answer to your first and main question, everything in our being and around us MUST follow laws of physics. Even if it is a law we have not found yet.

Going by your example, however...MAGNETISM is the answer. Just like recording on a tape, You are only altering the magnetic field of your hard drive to store information.
