Patent number: 7861255Abstract: The disclosure is directed to optical disks with a microstructured surface formed on a surface of the optical disk. The microstructured surface may be created to promote the adhesion and prevent the migration of a print material applied to the surface of the optical disk. The microstructured surface may be in the form of a plurality of wells or a plurality of discontinuous raised features in the surface. By forming a microstructured surface on the surface of the disk, the optical disk may not need an additional coating to receive the print material while also retaining the print material at a precise location on the surface. In addition, a plurality of standoff features may be formed in an outer surface of the optical disk to help prevent damage to the surface of the optical disk.Type: GrantFiled: May 23, 2007Date of Patent: December 28, 2010Assignee: Imation Corp.Inventor: Jathan D.

Patent number: 7785689Abstract: The invention provides for modifications to conventional optical data storage media to reduce the amount of raw material necessary in the media construction. More particularly, a portion of a thermoplastic substrate is modified to create one or more substantial void areas compared to a conventional substrate that defines flat parallel surfaces without void areas. The configuration, number, and size of the voids may be modified in order to substantially reduce inherent raw material cost while maintaining the specified physical thickness, clamping area, and mechanical stability of the medium.Type: GrantFiled: August 21, 2006Date of Patent: August 31, 2010Assignee: Imation Corp.Inventor: Jathan D.
