Hi Michael,Are you sure about the analog recording thing? I was speculating that whole track was simply written with some repeating pattern like 1s and 0s. Last night I was looking at the signals coming from a regular formatted disk and it shows many of the same patterns that are seen in service manual, with a lot of added noise and jitter. I figure that the noise and jitter came from the sector headers and actual data not being a consistantly repeating pattern.
