Question

When we move from outermost track to innermost track in a magnetic disc , density ( bits per linear inch)

A. increases

B.Decreases

C. Remains same

D. A or B

 

Plz explain

Answer 1

→ we move from the outermost track to the innermost track in a magnetic disk, then density(bits per linear inch) increases
→ The density, in bits per linear inch, increases as we move from the outermost track to the innermost track (this same phenomenon is present in a phonograph record).

Answer 2

See in some numerical question its directly mentioned whether density increase or remain same

but by default I think it increases as you we go from outer to inner track
