Answer:
1) A drive head, while in one position can read or write a circular ring, or band called a track. There can be more than a thousand tracks on a 3.5-inch hard disk. 2) Sections within each track are called sectors.

Platters
A platter is a round magnetic plate that is utilized for putting away information in a hard disk. It is frequently made of aluminum, glass substrate or artistic. A hard drive contains a few platters that are mounted on a similar shaft.
Tracks
The tracks are concentric circles around the focal shaft on one or the other side of every platter. Tracks are over one another on the platters are assembled into chambers which are then additionally partitioned into sectors.
Sectors
The sector is a disk's littlest open unit. Drives utilize a procedure called zoned recording in which tracks outwardly of the plate contain a larger number of sectors than those within.
Pits
An optical disk is a round disk which encode data or information as pits and lands on an exceptional material on one of its level surfaces. The land address "1" and the pits address "0" in the binary computation.
