Abstract
A component includes a micro-hologram layer, where the micro-hologram layer includes layers inert to light interleaved with layers of functional film. The functional film layers are made of a material that undergoes a change in its refractive index when illuminated by a light beam, yet undergoes no change in its refractive index when illuminated by a different light beam. The components may further include interleaved spacer films with multiple micro-hologram layers and other elements (e.g., servo layer, coatings, and the like) so as to comprise a data storage device. Methods of manufacturing the component and device are also disclosed.
