People forget the NeXT Cube originally came with a version of one these (magneto optic read outs based on Kerr Rotation); Jobs was a visionary for certain. I actually worked on a version of this (Cobalt-Platinum multilayers) for a summer internship with Mark Kryder at the Data Storage Systems Center; a formative experience for me. The Seagate technology described here is probably largely based on his work.
