Abstract
This IDC study explores the adoption of discrete track media (DTM) and
bit-patterned media (BPM) for the hard disk drive (HDD) industry through
calendar year 2012, and provides an in-depth analysis of the production process
needed to fabricate DTM or BPM disk media, including the capital equipment
requirements to support an industry transition to DTM disk manufacturing. As
part of this study, IDC provides an outlook for the timing of DTM and BPM
introduction, its cost compared with current disk media, and its forecast for
adoption in the HDD industry.
"Areal density continues to be an important metric for the HDD industry, but
the engineering challenges that the HDD OEMs must overcome to achieve this
growth in areal density are increasing in difficulty. Discrete track media and
its successor, bit-patterned media appear to be key technologies needed to
extend PMR technology in HDDs." - John Rydning, research director, Hard Disk
Drives
"But the process changes and costs necessary to migrate to these new
technologies are significant, and HDD OEMs must tread cautiously and time their
transitions carefully so that any migration is in step with market
requirements." - Jeff Janukowicz, research manager, Solid State Drives and HDD
Components
