C. Areal density: the amount of data per square inch on a platter

Page 195 Track density: This term refers to the space required by a particular number of tracks on a disk. Disks with a greater track density can store more information and offer better performance. ▪ Areal density: This term refers to the number of bits per square inch on a platter, and it represents the amount of data a hard disk can hold ▪ Bit density: This term refers to the number of bits a unit length of track can accommodate

A > Not to forget that Areal density also represents the amount of data a hard disk can hold

Area density refers to the amount of data that can be stored per unit area, typically measured in square inches. It is a measure of how densely the data is packed within a given storage medium, such as a hard disk drive or a solid-state drive. By increasing the area density, more data can be stored in the same physical space, allowing for higher-capacity storage devices. This is achieved through advancements in technology, such as increasing the areal density of magnetic storage media or reducing the size of memory cells in solid-state storage.
