Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 566

US Classification:

428694TS, 428694 TM, 428694 TC, 428694 SG, 428336, 428900, 428611, 428667, 427129, 427131

Abstract:

A magnetic media structure deposited on glass substrates without a NiP layer having oriented media (OR 1), high coercivity and high SMNR is presented. This media will significantly reduce the cost of making high quality media on glass substrates by eliminating the cost associated with additional steps of depositing a NiP layer and texturing that layer. First glass substrates are mechanically textured to have a surface roughness of about 1 to about 12. The first layer of the magnetic structure contains Cr and Ti with a Ti content of 27 to 63 atomic percentage. The second layer contains Co and Ti with a Ti content of 43 to 55 atomic percentage. The third layer is a Cr-alloy layer wherein the alloy is an element chosen from W, Mo, V, Si, Ti, Mn, Ru, B, Nb, Ta, Zr, and Pt. The fourth layer is Co Cr Pt and the fifth layer is Co Cr Pt B. Finally, the protective overcoat is typically a hard material that contains hydrogenated carbon.

International Classification:

E02D 29/14

US Classification:

404 25, 52 20

Abstract:

A concrete lid for an in-ground utilities box includes a plastic reinforcement structure filled with concrete. The plastic reinforcement structure includes one or more plastic sidewalls that protect the edges of the lid from damage. The upper and lower surfaces of the lid are exposed concrete (with the exception of the upper and lower edges of the one or more plastic sidewalls). The one or more plastic sidewalls laterally surround a plastic reinforcement grid, which is centrally located between the upper and lower edges of the one or more plastic sidewalls. The one or more plastic sidewalls can be integrally formed with the plastic reinforcement grid. The plastic reinforcement grid reinforces the concrete lid, eliminating the need for separate reinforcement material. Support struts can be used to support the plastic reinforcement grid while wet concrete is being poured into the plastic reinforcing structure.
