No, the floppy disk was really square and floppy. It was the original storage for the earliest PCs. Later there was a "floppy disk" that was smaller and hard. After that the round and hard CD.
floppy disk
Hard drive, CD, and Floppy disk
hard disks, floppy disk, cd-rom.
Secondary Storage
"Permanent storage", because the data does not disapear when the power is turned off.
The most common type of computer file storage is Hard Disk , it is in built with computer . External Storage is Like CD , DVD , Pen Drive , Floppy Drive .
This is a very retro question. Very few companies use floppy disks at all. Anytime they need reliable storage, storage of more than 1.4 megabytes, inexpensive storage, fast retrieval, shared storage, and immediate access, the hard disk is used.
In their basic form, floppy discs are common hard disks are the same technology. They both use magnetism to store and read data. They both use a spinning platter read by a horizontally moving read head. The key differences are that hard disks have the data and reader in the same package, this is why hard discs have evolved in storage capacity while floppy disks remained the same. It was necessary for the written layer of a floppy disk to have the same data density and dimensions as they had to be compatible with floppy disk drives. However with hard discs the drives and read heads could evolve along side the data layer. Hard discs now have metal platers, and store data at a much higher density. The speed of the mechanisms are much much faster. New technologies such as perpendicular storage can be added and have no impact on compatibility.

Hard disk drives, floppy discs, and VHS are some examples.
