Method and apparatus for microform updating

摘要

Apparatus and method for updating microform information recorded in a sequence on photographic film emulsion, including taking a desired portion of the emulsion carrying an image and bonding it to a primary base material either in the same sequence but with gaps left in the sequence or in a different sequence. The emulsion is bonded into sunken areas in the base material, the sunken areas either being formed by indented portions in the base material or by applying an apertured frame surrounding a flat base material.
