Filed:

Feb 13, 2003

Appl. No.:

10/366934

Inventors:

Jeffrey Shane Reiter - Palo Alto CA
Stephen Eric Barlow - Hayward CA
Zhiwei Cai - Fremont CA

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

C23C 1434

US Classification:

20419212, 20429821, 20429822, 20429826

Abstract:

A system and method for reducing and controlling the number of defects due to carbon inclusions on magnetic media is disclosed. A diamond like carbon protective layer is deposited on magnetic media using a rotary cathode target assembly. The target and cathode are cylindrical in shape and are mounted on holder that allows the target and cathode to rotate while holding a magnet fixed. The target surface is periodically swept in through a plasma which sputters off the surface of the target. This prevents the build up of redeposited material on the target and consequently keeps the target surface cleaner. The reduction of redeposited material on the target surface reduces the number of unwanted particulates which are ejected from the surface, manifesting themselves as disk defects.

Appl. No.:

15/998124

Inventors:

Kenneth Datkinson - San Francisco CA, US
Stephen B. Barlow - Providence RI, US

International Classification:

A42B 3/00
A42B 3/06
A42B 3/28

Abstract:

A system for preventing insects from entering the vent openings of bicycle helmets including a preferably elastic shell-shaped covering of an open mesh material wherein the mesh openings are sized to prevent insects from passing through such that when the covering or barrier is mounted over or in the helmet, the desired insect prevention is achieved.
