Due to the omnipresent
nature of computers, the necessity for an efficient and larger storage has been
drastically on the rise. The more the complex the system is, the more the storage
requirements become. Hard disks have a major role in satisfying the needs of the
computer users. Since storage density of hard disk is increasing at rate of 60%
per year  and is approaching its atomic level saturation, there is a need for
adapting some other technique to make maximum utilization of the available space.
With not many solutions in hand, this paper is a novel approach. The
basis of this idea is that when an external magnetic field is applied to an Elongated
Single Domain (ESD), the domains get oriented in the direction of the external
field. This specific property can account for the existence of more than two states.
The domains are oriented in different directions each representing a new state
unlike the conventional hard disks where only two directions are made use of.
Thus each individual bit field* of the memory is capable of representing more
than one state thus allowing octal, decimal, hexadecimal etc. representations
instead of binary representation.
In the today's cyber world, we are largely dependent
on computers. With the advancement of technology and complexity of computers,
the need for massive storage is mandatory. Hard disks have been a major storage
media for the past several years. Hard disks continue to shrink in size, gain
increased storage capacity and increased transfer speeds. The focus of development
has been on increasing the density. But this may ultimately lead to saturation
to atomic levels one day. Hence in this paper, on the basis of domain theory,
different states have been given to an individual bit field making it possible
to store more information on a single bit field without modifying its density.
