3. Although disks, CDs, and DVDs will hold data for an indefinite length of time, retrieval of the data on these media requires functioning players. As an analogy past generations have stored music on phonograph records and on 8-track tapes- both of which were considered "permanent storage" in their day-and now it can be difficult to find machines to handle either of these technologies. Similarly, over the years, storage media for computers have included paper tape (strips of paper with holes punched to reflect the data), paper cards (again with holes), magnetic tape (of varying widths), floppy disks (thin disks which were in 5 "in diameter). modern removable disks (3.5" now dominate the market), flash drives, SSDs, and so on. With this evolution of technology, some storage media used even just a few years ago may be unreadable on many modern computers. Come up a scheme to manage the data so it can be stored permanently for ever
