Abstract:
1. A hybrid structure comprising: a. a first region storing selectively retrievable data in a data layer of substantially uniform composition containing a substantially planar first level, b. a second region comprising a second track segment having a second track segment axis, a length of said second track segment having a second track segment longitudinal extent along said second track segment axis, a microscopic second track segment transverse extent normal to said second track segment axis, and a microscopic second track segment vertical extent normal to said second track segment axis and said second track segment transverse extent, wherein: c. said first region comprises a plurality of first track segment lengths, said first track segment lengths mutually displaced in a direction substantially normal to the first track segment axis of at least part of a first track segment length; d. said second region comprises a plurality of second track segment lengths, said second track segment lengths mutually displaced in a direction substantially normal to the second track segment axis of at least part of a second track segment length; e. said second region is displaced from said first region in a direction substantially normal to the first track segment axis of at least part of a first track segment length; f. said second track segment transverse extent exceeds said first data feature transverse extent; g. said first data feature vertical extent exceeds said second track segment vertical extent; and h. said data segment transverse extent is not less than said first data feature transverse extent.
