I had previously asked about a disk platter I was trying to identify. I have a couple of more pictures of it as well as some items from another drive. The latter is stamped "INFOMAG". By doing some www research I thought I had identified one or more of the principals in the company but got no reply to my emails. This is apparently a shortened version of Information Magnetics Corp. According to "Corporate Affiliations", that name was later changed to Computer & Communication Technology Corp. That name was later changed to Sunward Technologies, Inc. That company was later merged with Read-Rite Corporation. No other part numbers or IDs. If you recognize it I would appreciate the identification. Here's our web page with the pictures of the unknown items: http://www.cse.uta.edu/TheMuseum at CSE/Whazat.html TIA, Gil
