Abstract :
The progress of hard disk drive technology is reviewed, and future storage technology is observed. First, areal density growth, and improvement of performance such as data transfer rate and access speed are looked at, corresponding with the progress of magnetic materials. Then, state of the art high-density recording technologies are reviewed. The bit aspect ratio is considered with respect to the trends on precision process of pole tips, and high output sensor evolution. Finally, future of information storage is examined, and storage technologies toward 1 Tb/in/sup 2/ recording are investigated.
