Question

Answer

Magnetic Disks Structures:

A magnetic disk is a storage device that uses magnetization to store and retrieve digital data. It consists of one or more rotating disks coated with magnetic material and read/write heads to access the data. The surface of a platter in magnetic disks structures is logically divided into circular tracks.

Circular Tracks:

The surface of a platter is logically divided into circular tracks. These tracks are concentric circles on the surface of the disk. The tracks are numbered from the outermost track to the innermost track. Each track is further divided into sectors, which are pie-shaped wedges on the surface of the disk.

Sectors:

Each sector on a track stores a fixed amount of data. The number of sectors on a track can vary depending on the disk's format and capacity. Sectors are numbered sequentially starting from 0 to the maximum number of sectors on a track.

Conclusion:

In conclusion, the surface of a platter in magnetic disks structures is logically divided into circular tracks, which are concentric circles on the surface of the disk. Each track is further divided into sectors, which are pie-shaped wedges on the surface of the disk. Sectors are numbered sequentially starting from 0 to the maximum number of sectors on a track. By dividing the surface of the platter into circular tracks and sectors, it becomes easier to organize and access the data stored on the disk.

Answer

Magnetic Disks:

Magnetic Disks provide the bulk of secondary storage for modern computer systems. Conceptually, disks are relatively simple. Each disk platter has a flat circular shape, like a CD. The two surfaces of a platter are covered with magnetic material. We store information by recording it magnetically on the platters.

A read-write head "flies" just above each surface of every platter. The heads are attached to a disk arm that moves all the heads as a unit. The surface of a platter is logically divided into circular tracks which are subdivided into sectors.
