What is a floppy disk

The English abbreviation for floppy disk is Fioppy disk, which is the earliest removable media used on the computer. It is used as a removable storage hardware. Applies to small files that need to be physically moved. Floppy disk read and write is used by the floppy drive with evil is the floppy disk drives to complete.

The role of floppy disk

Floppy disk drives are designed to receive removable floppy disks, which are commonly used in 3.5-inch floppy disks with a capacity of 1.44MB (eight inches and five one-fourth inches, of course). Floppy disk access speed is slow, the capacity is small, but can be loaded to unload, easy to carry. As a removable Storage method, it is an ideal choice for small files that need to be physically moved.

Storage format for floppy disk slices

Refers to how many concentric circular tracks each side of the disc is divided into, and how many sectors each track divides into storage information. A sector is the basic storage unit of a floppy disk, each of which reads and writes to a number of sectors called clusters. The earlier floppy disk was 5.25 inches, single-sided 180KB. Later appeared double-sided 360KB. And then there are 3.5-inch double-sided 720KB. These are all low density floppy disks. Then came the 5.25-inch double-sided high-density 1.2MB and 3-inch double-sided high-density 1.44MB, until the last appeared 2.88MB. These all belong to high-density floppy disk. 5-inch floppy disk has been eliminated, 2.88MB is only a flash in the pan, the market can now buy only 3-inch double-sided high-density 1.44MB floppy disk.

What are some things to pay attention to when buying a floppy disk?

1, first check the appearance

See whether the appearance of the processing is excellent, the general quality of the disc surface is very smooth. More evenly consistent and is no scratches. There's no mold. If you can see some of the obvious hungry circle, the relative quality of water is relatively poor. If scratches are obvious, the basic floppy is also bad and useless.

2. Brand identification

Now people are very concerned about brand awareness, including users need to buy a floppy disk is also needed to pay attention to, all of us in the purchase of floppy disk first to ensure quality, and then after the sale and so on are to be considered.
