The floppy disk capacity is low compared to many of the digital storage formats that are available today such as CDs, DVDs, hard disks, and data tapes. This makes floppies not suitable for digital scrapbooking storage projects.
The information or data on a floppy disk is laid out in concentric circles which are called tracks. This differs from optical media where the data is laid out in a spiral pattern. The tracks on a floppy disk are further divided into wedges or sectors.
The number of sectors per track on a diskette is constant. The actual data that is stored is represented on the disk via the alignment of the magnetic particles in the binder layer of the diskette.
With the application of a magnetic field, the magnetic particles can aligned themselves in one of two ways. One orientation is made to represent a “1” in the binary code and the other orientation the “0” in the code. By varying the orientation, the binary code for the stored information is formed.
The floppy disk capacities vary depending on the size of the disk and the format. There are various designations of disk storage capacity and some of these are summarized below for the various sized disks. The list below indicates some of the most common capacities. There were several other floppy diskettes with different storage capacities and different sizes available as well, but these are not shown as they were generally less popular.
