Abstract:

Magnetic recording technology has come a long way, since the introduction of the first hard disk drives (HDD) in 1956. The areal density has grown by a factor of 200 million times and the HDD has stayed as a main candidate for mass storage of information. In order to maintain its lead over other competing technologies, HDD industry continues to invent several technologies. Having introduced perpendicular recording technology in the last 5 years, the industry is looking at introducing bit-patterned media or heat-assisted magnetic recording in the next five years. The researchers - looking at a longer term - are investigating 10 Tbits/in2 as the next major milestone. The issues and probable candidates for 10 Tbits/in2 magnetic recording technology are described from a material perspective.
