Development
Everyone wants faster, cheaper disks with increased capacity. Therefore, hard disk technology undergoes
an explosive development. There are two major trends in this development:
l Data are packed increasingly closer with new coating and read/write techniques.
l The disks rotate faster and faster.
It is my impression that the various hard disk manufacturers alternately develop new, sophisticated
technologies, which spread with the speed of lightning to other brands. A couple of years ago, IBM
suddenly introduced lightning fast disks with new MR heads. Everyone uses those today. In 1997
Quantum introduced the Ultra DMA interface, which all other manufacturers now use as well.
