Full Version: # Revolutions

If you set the # of revolutions to >1 and read in a track, what's the expected behaviour when clicking the "write track" button? Does it average the results and write back one revolution? Does it write all of the buffered revs sequentially? Or does it just write the first rev back?
It writes back whatever you have selected as the FLUX START and FLUX END in the buffer. If you don't set these, the entire 2 revolutions are written (sequentially from the buffer).

The easiest trick to duplicate ANY track is this:

Read 2 revolutions.
Go to the start of the 2nd revolution and look for the write splice. You could find a gap, but the best is to find invalid data.
Move the cursor to where you want the writing to end (on the write splice).
Click the SET FLUX END button.

Notice the area after where you set the flux end will be gray'd out. If you click the WRITE TRACK button now, the data in the buffer will be written up to the point where you selected the flux end. This means 1 full revolution and one partial revolution. Since its accurate to +/- 1 bit (typically for drive speed variations) the write splice will appear exactly where you wanted it.

If you wanted to frame (rotate) a track to the index, you could do that by reading 2 revolutions and setting the START FLUX and END FLUX positions.

EDIT: I just noticed the MFM mode does not show the flux start/end, only FLUX and GCR modes do. I will look at that today.
