Abstract:
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 [1] 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. The merits and demerits of this technology have also been discussed.
Keywords:
bit field* : The smallest possible storage area.
