![]() ![]() ![]() DS – Double Sided or DD – Double Density – 360 KB.SS – Single Sided – 110 KB or 160 KB storage capacity.The most common floppy disk capacity was the double-sided high density one. DSDD – Double Sided Double Density – 1.2 MBįour different version of this format were produced.DSSD – Double Sided Single Density – 500 KB.SSSD – Single Sided Single Density – 250 KB.After that a variety of other versions were introduced with high capacities as listed: The first 8-inch floppy had a capacity of a very low 80 KB. 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. The list below indicates some of the most common capacities. There are various designations of disk storage capacity and some of these are summarized below for the various sized disks. The floppy disk capacity vary depending on the size of the disk and the format. By varying the orientation, the binary code for the stored information is formed. One orientation is made to represent a “1” in the binary code and the other orientation the “0” in the code. With the application of a magnetic field, the magnetic particles can aligned themselves in one of two ways as shown in the following schematic image. The actual data is represented on the disk via the alignment of the magnetic particles in the binder layer of the diskette. It is the magnetic particles on the disk that store the information. Storage of Information on a Magnetic Disk The number of sectors per track on a diskette is constant. The tracks on a floppy disk are further divided into wedges or sectors. This differs from optical media where the data is laid out in a spiral pattern. The information or data on a floppy disk is laid out in concentric circles, which are called tracks. Therefore, it is obvious that floppy disk capacity is not suitable for digital scrapbooking storage projects. Video files of any decent quality are much larger than audio and picture files. A typical high quality digital photographic image is at least 10 MB and usually larger than this. For example, a standard audio track of CD quality is about 50 MB. ![]() In comparison to CD and DVD optical disc media, it would take about 486 of 3.5-inch floppy disks (1.44 MB capacity) to fill a CD and 3264 of 3.5-inch floppy disks to fill a single-layer DVD. ![]()
