Abstract
Magnetic hard disk drives are the dominant digital storage. It is
estimated that 1.4 B drives will be shipped in 2016, storing zetabytes
(1021) of information. Current shipping HDD products have a storage
capacity over 3.0 Terabytes, and these products will exceed 10 TB
capacities within a few years. Recently Seagate announced a demonstration
of 1 Tb/in2 magnetic recording density using HAMR technology. In the past
year HDD areal densities have slowed to 20-25% annual CAGR and new
magnetic storage technologies must be introduced soon to support higher
areal density growth and maintain the competitiveness of HDDs. This
presentation will evaluate advanced processing techniques; as HAMR, PBM,
CPP/GMR heads, shingled write and 4K sectors that allow higher storage
capacities and lower $/GB. A roadmap to 10 Tbit/in2 will be proposed, and
each technology appraised within the guidelines of allowable capital
equipment expenditures per drive, processing costs and unit price per
GByte. Projections for the growth of capital equipment for manufacturing
process, process test and metrology will be examined to support these
technology transitions. The talk will also show the expected trends for
HDDs vs. competing storage technologies such as flash memory
