312-49 Question #640: Real Exam Question with Answer & Explanation

The correct answer is A: Volume density. Hard disk data density is measured in three standard ways: Track density (the number of tracks per unit length, typically tracks per inch), Linear (or recording) density (the number of bits per unit length along a single track), and Areal density (bits per unit area, combining tr

Question

Which of the following does not describe the type of data density on a hard disk?

Options

AVolume density
BTrack density
CLinear or recording density
DAreal density

Explanation

Hard disk data density is measured in three standard ways: Track density (the number of tracks per unit length, typically tracks per inch), Linear (or recording) density (the number of bits per unit length along a single track), and Areal density (bits per unit area, combining track and linear density). 'Volume density' is not a recognized or standard term used to describe hard disk storage density, making it the answer that does not belong.
