摘要： A single, or common, ion beam source is utilized for ion beam deposition (IBD) of defect-free multilayer coatings, e.g., multilayer, carbon-based protective overcoats for magnetic and/or magneto-optical (MO) data recording/information storage and retrieval media such as hard disks. According to the inventive methodology, a plurality of source gas supply means for supplying a single IBD source with different source gases for each of the layers of the multilayer are selectively operated in “vent” and “run” modes by means of a plurality of valves, the opening and closing of which are determined by a programmable gas flow controller. The inventive method and apparatus advantageously provide IBD of multilayer coatings with minimum cross-contamination of individual layers, at a reduced equipment cost and size obtained by elimination of the need for separate ion beam sources and associated vacuum pump for each constituent layer of the multilayer.

摘要： A collimator system is disclosed for use in an in-line pass-by sputtering system during the fabrication of recording media to improve the data storage density and read/write performance characteristics of the media. The collimator system includes a collimator shield and a collimator honeycomb. The shield includes a rectangular tube having a flange and a frame at inner and outer ends, respectively. The various components of the shield in part serve to prevent possible contamination of substrates due to target atom accumulation on the chamber walls during the sputtering process. The collimator honeycomb is provided for blocking target atoms from contacting the substrate at low incident angles. The collimator honeycomb is comprised of a plurality of collimators which are identical to each other. In a preferred embodiment, the collimators have a hexagonal cross-section taken from a perspective perpendicular to the substrate. The collimators may also have other geometric shapes. It is also contemplated that more than one collimator honeycomb level be used in alternative embodiments.
