Digital Recording: What is to be Done?

Digital magnetic recording is probably as old as the earth itself. The earth's magnetic field was indeed retained by lava becoming solid a hundred million years ago, and the hundreds of flux reversals that have been occurring since that time are now stored in the Atlantic ocean deeps within a natural “tape” of lava flow running at a few inches per year. More recently, the first experimental achievement of alternate magnetization of a steel wire was reported by Arago to the French Academy of Sciences in 1820.
