Introduction
Since the inception of the modern computers in the late 1940s, computing systems have continually grown in complexity, both in hardware and in the software associated systems. This complexity is due to two factors: first, the tradeoffs in cost/performance versus size of various memorystorage systems, and second the way users organize and use data.
Modern computing systems consist of four hardware components: the central processing unit (CPU), the main memory, the secondary storage (disks, tapes, CDs, etc.) and the input-output devices that interfaces with humans. Since the beginning of the modern computer era in the late 1940s and early 1950s, the need for larger storage capabilities has become increasingly apparent. The need for larger storage is due mainly to the vast amount of digital data including graphic, audio and video media.

All computations, either mental, mechanical, or electronic require a storage system of some kind, whether the numbers be written on paper, remembered in our brain, counted on the mechanical devices of a gear, punched as holes in paper, or translated into electronic circuitry. This study reviews the evolution of the storage systems from early mechanical systems to optical storage technology. Because of the importance of the storage systems in computing, evolution of the storage systems is directly related the CSIS 550-History of Computing.
Floppy Disk Drives / Floppy Disks
Floppy disk drives were originally introduced commercially as a read-only device in the early 1970s. These early floppy disk drives were used to hold microcode and diagnostics for large IBM mainframe computer systems. These disk drives were using 8-inch floppy diskettes recorded on only one side. By changing these diskettes inside the floppy drive, technicians could easily update the microcode to the latest revisions or load diagnostics easily. The storage capacity of these early readonly drives was less...
