Hi!, a workmate told me that the tip lifts up and then goes down between each trace and retrace. Is that true?

I thought that it just went back an foward in a v shape path. Knowing this might help us understand some images with strange borders.

Thanks in advance!

Normally the tip follows the v shaped path that you describe, but there is a mode called 'lift mode' that is commonly used in MFM and EFM.  In lift mode, the tip is lifted for every other pair of trace and retrace.

Hi Luis,

 

I know it's been quite a while since you posted this question, but did you ever figure out why you are getting images with "strange borders".  We might be having the same issue.  Our issue is that only on ONE side the image is blurred and the trace/retrace overlap is really poor (seems offset).  Does anyone have an idea about what could cause this?  Thanks.
