For the past sixty years humans have increased their capability of mastering the information storage technology based on electron charge and spin at an average of two orders of magnitude per decade. In 1956 IBM introduced the RAMAC 350 Disc Storage Unit which was capable of storing 2 kilobytes over the area of 1 square inch. Assembled with covers, the 350 was 60 inches long, 68 inches high and 29 inches deep. It was configured with 50 magnetic disks containing 50,000 sectors, each of which held 100 alphanumeric characters, for a capacity of 5 million characters. Disks rotated at 1,200 rpm, tracks (20 to the inch) were recorded at up to 100 bits per inch, and typical head-to-disk spacing was 800 microinches. Today’s hard drives make use of technologies which push the boundaries between classical and quantum mechanics realms while approaching 1 Terabit/in^2 in storage density. In this talk we will take a closer look at the current research efforts for surpassing the physical constraints of the superparamagnetic limit in magnetic storage systems and briefly dive into the world of quantum states systems where information could be stored at the subatomic spatial limit.
