Sector is the smallest unit on Hard disk identified & addressed by File System.
A sector
A magnetic disk is organized with circles called tracks. These tracks (think of the race track around a field) are the path followed by the magnetic head when reading and writing the signal. The data is organized into short sections, called sectors. This is just a convenient size of data, rather like a page is a convenient size within a book. When you read or write data, you do not need to follow the whole track as it spins, just as many sectors as contained the data you are interested in. On the most modern disks, each track holds a megabyte, more or less, and each sector is typically 4096 bytes. The whole disk may have hundreds of thousands of tracks.
Transfer time = revolution time / #sectors per track
It's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).
It is the magnetic elements in a magnetic disk that are used to store information.

No. Floppy disks are magnetic media that rely on magnetic polarization to write data to the disk much like a hard drive. Unlike CD media they can be erased by a strong magnet field that effectively scrambles the data tracks.
The smallest addressable unit of storage on a disk is called a sector.
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
In a way, yes. The material that makes up the "disk" in a floppy is Mylar, a magnetic substance. Data is stored on the Mylar disk in the form of magnetic charges.
