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
