Consider a hard disk with the following specifications.

$3\mathrm{.}5$in in diameter

$10$ platters, and $2$ surfaces per platter

Capacity: $10$GB

Number of cylinders: $256$

Suppose the inner $1\mathrm{.}5-$inch diameter is not used for data. Consider the following two options.

Option A: Each track has the same number of sectors$.$

Option B: The number of sectors in the innermost track is $50\%$ of the average number of sectors per track, and the number of sectors in the outermost track is $200\%$ of the average number of sectors per track.
