Given Information:
A rotating disk in which number of bits per track is constant is given.

Explanation of Solution
Capacity of disk:
It is given that there is a rotating disk whose number of bits per track is constant. It is assumed that:
“r” denotes the radius of the platter and “
- In a rotating disk, the number of bits per track will remain same which depends on the circumference of the innermost track.
- The most inner track can also be considered as a hole and the number of bits per track will increase if the hole is large and vice versa.
Hence, according to the given information:
“r” denotes the radius of the platter and “
In a rotating disk, the radius of platter is greater than the radius of the hole which can be written as below:
Hence, the value of x should be less than 1 in order to maximize the capacity of the disk and the value of x ranges from “
