Which of the following does not limit how much information can be stored on a CD or DVD?
A
Option A: Machine limits on how small pits can be made.
B
Option B: Wavelength of the light used to read it.
C
Option C: Diffraction limits on the pit size.
D
Option D: Diffraction limits on the track spacing.
Homework Answers
I think option (A) - Machine limits on how small pits can be made
Reason - there is no standard size of pits on a CD or DVD..the machining of surface can be different
