However, I never see anyone talking about the small gold plated bit inside the actual read eye in all HDD's. I have found this same small gold plated part in every type of disk reader, ETC ... CD drives, DVD Drives, Blu-Ray and HDD's.

So my question is... Is there anyone else out there that collects these for a later sale.
I have been saving bushels of the "arms" but I've yet to see any gold plating in a HD, could you enlighten me with a pic. please.
