Re: CD Tracks and Pits
In reply to Stephen Barrett, Oct 29, 2012

Both lens have a PZO/Poland branding:

The lens facing the CD: 10/0.24  160/-

The lens facing the G2: 40/0.65  160/0.17

I tried the setup with 3 DVDs (rewritable, a dual-sided (each side has one movie, strange invention), and an ordinary one). Only one of them showed some visible pattern, but unfortunately it was impossible to see any track structure to measure, it was just a field of random noise unworthy to photograph.

Maybe the next candidate will be more successful
