Marty, Deposition Thin material films - only a few atomic layers thick - are deposited on a substrate by different techniques . Why it is important-- (from RDRT home page) <<In creating new products for storing more data per disk, Read-Rite must design MR elements to be extremely thin (about 50 molecular layers) and quite narrow (less than the diameter of a red blood cell). Moreover, the MR elements cannot short out electrically with shields, which are relatively thick, wide and tall.>> Also from RDRT <<Read-Rite has installed state-of-the-art deposition equipment to meet the challenge of producing the very thin layers required by Spin Valve technology,>> readrite.com BTW, The measurement of these layers and the extreme tolerances necessary when you have a head "flying" so very close to the platter (which is spinning at 10,000rpm) is a fascinating subject. Words like "very close" and "extreme" don't really do justice to the technology. Yogi
