Hard drive   Leave a comment

I came into possession of a spare hard drive, so onto the dissection table it went:

And here is a zoom sequence of the read/write head. After a ‘normal’ zoom, we removed the head and took some images from the side- both sides of the hard drive platter are used for data (presumably)… Then, we placed the head under the microscope for reflected DIC- the final image is of the metal support at 160X, and shows a very unusual surface finish. Then we separated the halves and took images of the actual read/write device. Enjoy!

The platter itself is possibly the most perfect mirror I have ever seen- absolutely flat, no coating defects. Again, the level of technology we take for granted is truly amazing. Unfortunately, I can’t get the bearings open- those would be pretty fantastic as well.
