Abstract
An optical disc data storage system includes an optical disc for storing information in an optically readable format on a data surface. The slider is positioned proximate the data surface of the optical disc. An actuator coupled to the slider selectively positions the slider relative to the data surface. An optical waveguide having a radially graded index of refraction extends between a first end positioned proximate the light source and a second end coupled to the slider and positioned proximate the data surface. The optical fiber carries light therebetween.
