|Computer storage density|
Computer storage density is the quantity of information that need to be stored on a given length of track of a computer storage medium. The higher computer density is more used and is desirable; it allows more data to be stored on the physical space. Computer storage density has a relation to storage capacity of a medium. The recording density is measured in the following ways: They are linear recording density:
The linear recording data is used to store data on concentric tracks of surface of the diskette. The recording density of computer storage density is just 17,434 bits per inch. The computer storage density can also be surface density: The diskette can store 80 tracks of data at a spacing of 135 tracks per inch with the innermost track at approximately 10.5 millimeters radius and the outermost track is at approximately 25.5 millimeters radius. The tracks occupy a surface storage area of approximately 1700 square millimeters. The recording density is 6,940 bits per square millimeter.
The physical density of computer storage density cans physically measures for a volume of 25,380 cubic millimeters. The physical density of computer storage density is 465 bits per cubic millimeter. The different storage mediums are compared to measure the efficiency of the storage. The modern storage densities are quite high is approximately 5,020,000 bits per cubic millimeter. The computer storage density of digital magnetic tape is usually measured in bytes per length; the other media in bits per square millimeter of surface area.
The computer storage density media will store data in volumetric space, making volume computations more relevant. Also, storage densities computed for comparison of technologies usually ignore physical containment; that is, memory density is computed based upon the number of bits relative to the surface of the integrated circuit, rather than the surface of the encasement. There is a theoretical upper limit to the amount of information that can be stored in a finite space. This limited information density limits the theoretical maximum information capacity of any given object. Practically speaking, technology is many orders of magnitude away from this limit.
Computer storage density is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume; of a computer storage medium. The computer storage density is of higher density, it allows greater volumes of data to be stored in the same physical space. Computer storage density has a relationship to storage capacity of a given medium.
The capacity of a computer storage density could be measured in these ways:
The linear recording density could be able to store on surface of the diskette. The maximum recording density of the computer storage density is of 1 inch for the innermost track is 17,434 bits per inch.
The Surface density: The diskette will store 80 tracks of data at a spacing of 135 tracks per inch (5.05 tracks per millimeter) with the innermost track at approximately 10.5 millimeters The computer storage density of the diskette physically measures 94 × 90 × 3 millimeters. The physical density by volume is 465 bits per cubic millimeter. Computer storage density is compared by density in order to measure the efficiency of the storage.
