On my Shugart and Siemens 8 inch drives I've used a heavy felt pad that I made using a steel punch. Then super glued it to the pin that snaps into the pickup arm. I've had the snap pin break and have successfully used a small nylon bolt and nut, which has the pad glue to it. I have tried small pieces of Teflon, cloth, plastic, but found that the heavy felt is the easiest to get to work and doesn't seem to harm the media.

Does anyone have some good hints on what and how to replace them? I have a CDC 8 inch floppy drive with a missing pressure pad. Tried to put some half a millimeter felt cloth with some double adhesive tape to replace it. But it didn't work very well. If I gently pushed the upper pressure pad arm it started to read at least. But it looks like it is possible to over-do it. I added more padding and then it probably got too thick since it now failed again. I guess that if there is a bit too much pressure the signal might be too high in the input amplifier leading to distortion? What is the best pressure pad material and what are you usually replacing it with? /Mattis
