hard disk

a computer data storage medium that consists of a rigid disk with an electromagnetic coating allowing information to be transcribed onto and from it. Permanently mounted in a dust-proof container, a hard disk has a storage capacity many times that of a diskette. Also called hard drive. Compare diskette.

From this piece of fundamental physics, the tape industry knows that a coercivity increase and a reduction in the magnetic thickness of the media is the primary direction to pursue as already demonstrated by magnetic disk technology.
Some vendors who have a vested interest in selling magnetic disk systems have tried to narrowly define ILM as containing only layers of hard disk systems with varying levels of performance, reliability and cost.
Holographic storage uses the entire thickness of the media, unlike magnetic disks that only use the surface on which to record data, creating volumetric or a 3-D recording efficiency.
It is likely that the rate of increase for magnetic disk areal density will start to drop below historical rates annually, due to the greater difficulty in making the new technology work.
It's a compelling architecture, which addresses the demands of a record archive in a way that magnetic disk and tape archives cannot.
The dominant and most popular storage technology is magnetic disk, as it contains nearly all of the world's mission-critical data.
Approximately 10% of the digital data produced in the world resides on magnetic disk storage and an estimated 90% of digital storage resides on removable storage media such as tape, optical (CD, DVD) or small-diameter removable disks.
