Which outcome limits data density on optical disks?

💡 Explanation

The diffraction-limited focused spot size limits minimum feature size set via Rayleigh Criterion, because resolution scales inversely to aperture and wavelength. Therefore, higher data density is unattainable rather than laser breakdown or thermal expansion, representing limitations at high power or temperature.
