CNET writes the hard drive industry is divided on future technologies:
To keep progress going, the first disks based on new technology will need to enter the market around 2011. Competitors differ, however, on how and when ideas for revamping drives should become reality.
Seagate Technologies, the world's largest drive maker, wants to first adopt a concept called "heat-assisted magnetic recording." This involves heating microscopic cells on the disk platters as part of the recording process.
